Last spring, Justino Jimenez left his kitchen job with Marc Vetri at Vetri and Amis to chase his dream of owning his own restaurant.

And he did it - opening Los Jimenez Mexican Cocin at Sixth Street and Oregon Avenue in South Philadelphia. Solid little spot in a former deli with a few tables, a flat-top grill, and a spit bearing the porky-pineapple makings of sublime tacos al pastor.

But onward and upward. Two months ago, Jimenez sold the place, which still bears his name.

He's just taken over Logan Square Pizza at 21st and Race Streets (215-496-9111), behind the Franklin Institute and just off the Parkway. It has a spacious, utilitarian dining room.

Rather than gut the place and shake things up too dramatically, he has simply added Mexican dishes to the menu.

Ergo: It's now Logan Square Pizza & Cocina.

You can get pizza, salads, and hoagies. You can get tacos, quesadillas, and burritos.

You can also get a little of both: pizzas topped with the usual ingredients, as well as chorizo or pastor. One night just before Thanksgiving, Jimenez whipped up a turkey mole pizza - a thing of beauty. The turkey breast had been brined for 12 hours before being roasted, his rich mole served as the sauce, and the cheese decorating the tip was ricotta salata - "the same cheese I used for gnocchi," he said, winking.)

Mexican dishes are $9.95 (most quesadillas) to $12.95 (alambre).

It's BYOB, and don't skip the flan for dessert.
