A South Philly garage is reborn as a date-night destination for oysters, cocktails, and polished vibes

My chatty Uber driver was born and raised in South Philly and so, as we threaded our way through the cozy rowhome blocks east of South Broad Street, he reveled in reciting the personal histories behind every deli, seafood market, corner taproom, and red-gravy pasta joint we passed. But even he seemed to be momentarily flummoxed as we pulled up to Tesiny, on the 700 block of Dickinson Street.

A century-old corner brick building that for much of its life was an auto-repair shop had been completely transformed. Its garage doors were replaced with broad paned windows that glowed amber with the inviting tableau of a bustling restaurant inside. Diners clinked glasses of pink martinis. Chefs were illuminated by the flicker of a live-fire grill in the central open kitchen, where oysters were being shucked at the U-shaped counter, to be dispatched on icy plateaus to date-night duos across the room.

The long bar near the entrance, deftly lit to illuminate its soigné design touches — the rich walnut wood accents, the purple-and-white tiled floor, the smooth curves of a backbar stocked with uncommon sherries — radiated a magnetic glamour.

“Let me know how it is!” he said, as I exited the Uber. I promised a full report.

In a dynamic old city constantly reinventing itself, we could do far worse than watching an industrial space be reborn as such a lovely restaurant. More specifically, you should be so fortunate to have Lauren Biederman be the one to do it.

Biederman, 30, is a bright talent who knows how to turn her quirky hunches into success. She’s best known as the area’s lox-and-caviar queen, after pursuing a “weird idea that popped into my head while driving” — that what Philly really needed was an old New York-style boutique market for hand-cut smoked salmon, fresh bialys, and brunch boards. In fact, we did. Five years after opening Biederman’s in the Italian Market, she’s now also serving caviar bumps from a kiosk beside the Four Seasons Hotel and about to open another Biederman’s near Rittenhouse Square, where Jewish prepared foods will be sold alongside the smoked fish.

But Biederman was a restaurant person before her retail success. The Vermont native worked at Oloroso, where she found her passion for wine, then got into bartending, working at Zahav and several Schulson Collective restaurants, including Osteria, where she met Devon Reyes-Brannan, 30, now her longtime boyfriend and partner at Tesiny. (The name, pronounced “TESS-iny,” is a reference to her late grandmother’s address in Connecticut. The two shared a love of seafood.)

Biederman designed the room and nailed the elegantly sultry mood, with the dark brown ceiling and light floors keeping it cozy while the mellow soundtrack shifts throughout service from Sinatra to Sadé, then to hip-hop beats for the livelier later hours. Good spacing between tables keeps conversation possible.

There’s an admittedly amorphous, on-trend quality to Tesiny — the raw bar, craft cocktails, and a chef’s-counter grill turning out shareable plates that resist easy classification as appetizers or entrees — that could just have easily landed in a buzzier restaurant district like Fishtown or Rittenhouse Square. But there’s an extra pulse of intimacy in finding this polished 50-seat oasis in the heart of residential Dickinson Narrows, a hotly debated neighborhood within a neighborhood just east of East Passyunk. It’s upscale, averaging $80 per person for food and drinks, but already resonating as a destination, with up to 100 diners on busy nights.

It succeeds on its posh vibes, but also the skill of its players to strike the right tone, from the well-informed (but never pushy) servers to chef Michael Valent, 36, with whom Biederman worked at Zahav. There’s nary a noodle on his menu — a rarity in this neighborhood.

Valent instead deftly draws on an array of multicultural influences without the food ever feeling overly contrived, largely due to the breadth of his experience, including time in Boston, New Orleans, and Philly (at the French-themed Good King Tavern, Superfolie, and Supérette). One moment you’re savoring a tuna crudo dusted with coconut and aji chili spice. The next you’re savoring a tender grilled Ibérico pork collar with silky pureed squash and smoky collards that recall Valent’s stint in New Orleans working for Donald Link at Cochon. Another favorite, a crispy-skinned branzino fillet over a Basque-style pipérade of Jimmy Nardello peppers, is an inviting jaunt to the Mediterranean.

The raw bar is always a smart place to start. The trio of ever-rotating East Coast oysters, from Canadian Eel Lakes to Sunken Meadows from Massachussetts, comes with a classic mignonette that benefits from being composed à la minute every time, so the shallots retain their bite (rather than pickle) in the rosé vinegar and still-fragrant fresh-cracked peppercorns. The shrimp cocktail was notably tender and flavorful from a citrus-scented poach. And the crudos were also tasty, although I preferred the juicier early version of the scallop crudo, bathed in jalapeño-spiced honeydew-cucumber water, to the more sparely dressed current setup, with smoked olive oil and Korean chili flakes.

A starter of creamy crab salad laced with chorizo oil conveniently cradled in endive spears was solid, but also perhaps a bit boring in a passed-hors d’oeuvres kind of way. It reflected an occasional finger-food aesthetic here, a propensity to lend familiar favorites extra polish for elevated, no-fuss nibbling; that never, however, came with any culinary shortcuts.

The tidiness impulse is especially clear with Tesiny’s labor-intensive chicken lollipops. Drumsticks of Green Circle chicken are “Frenched” to offer a clean bone handle for the poultry mallets that are double-crisped in rice flour, like Korean fried chicken. Glazed in an orange hot sauce made with Fresno chilies and infused with seafood trim (shrimp shells and scallop “feet”), the lollipops are visually appealing. But for a dish that also wants to evoke Buffalo wings, the sauce’s subtle flavors aren’t quite punchy enough for the maximum impact.

Restraint was not the issue with my favorite seafood starter here: a platter of char-broiled Indian Cove oysters that arrive in a pool of Calabrian chili butter, which requires at least one order of Mighty Bread sourdough to mop up from the shells. Whatever crusts are left over, you can swipe through the silky white bean purée that sits beneath the tender grilled octopus topped with harissa-spiced olives and fennel.

Valent’s winter green salad was also remarkably and unexpectedly delicious, its crunchy Little Gem and frisée greens dressed in a citrusy Champagne vinaigrette balanced by toasted almonds and the nutty Alpine richness of shaved Comté.

What to order from Tesiny’s gorgeous bar to accompany all this food? The well-crafted cocktails, many infused with fortified wines, are the most popular place to start. I especially enjoyed Not a Fender, a briny pink riff on a Gibson martini made with pickled red onions, olive oil-washed gin, and a splash of manzanilla sherry. And Tesiny’s thoughtful non-alcoholic offerings were so appealing that we ordered the blood orange-thyme fizz topped with creamsicle foam — and loved it — after spotting another couple order it across the chef’s counter.

To pair with the handful of larger plates clustered at the bottom of the menu, it’s worth exploring the wines, an interest of both Biederman (who’s passed her Level 3 Wine and Spirits Education Trust exam) and Reyes-Brannan, a front-house veteran from Tria and Laser Wolf. Reyes-Brannan is partial to the food-friendly acidity of high-altitude wines from Europe, but he’s also been an enthusiastic ambassador for a Mexican version of nebbiolo from Casa Jipi. Lighter and juicier than Italian iterations, it’s a fine match for the juicy wagyu culotte steak topped with cornmeal-fried oysters. It works equally well with the earthy grilled mushrooms that came dusted with chimichurri over a plate of warm polenta (recently updated to farro risotto).

The nebbiolo was also a good match for Tesiny’s single best bite: a 5-ounce burger special called the Lil’ Kahuna, made from the trim of bluefin tuna belly and Ibérico pork shoulder. It’s a remarkably meaty patty with a subtle shade of rich tuna on the finish that shows off Valent’s ability to experiment with something new. It’s limited to just eight or so per night, which means it’s worth coming early. The effort also bodes well as Tesiny prepares to grow its menu and take some chances with larger plates for two, perhaps as soon as this spring.

Dessert for two here is already a thing. And you’ll likely be dueling spoons for the espresso-chocolate mousse that Valent serves like a sundae topped with a wave of whipped cream, caramel cocoa nibs, and real maraschino cherries. Order a raisiny sweet pour of Pedro Ximénez from the impressive list of fortified wines — another quirky passion of Biederman’s, rooted in her days of studying abroad in Mallorca and her time at Oloroso.

Is Philly ready for a renaissance of Bual Madeira and vintage Kopke Port? If Lauren Biederman has a hunch, I wouldn’t bet against her. Tesiny is more proof she has a vision worth paying attention to.
