Harvest Seasonal Grill & Wine Bar, which opened Sunday in Glen Eagle Square, is quite a departure for chiropractor-turned-restaurateur/motivational speaker Dave Magrogan, whose pub holdings include Kildare's and Doc Magrogan's.

To conceive Harvest (573 Wilmington West Chester Pike, Glen Mills, 610-358-1005), Magrogan looked to his upper-middle-class, thirtysomething suburban world of SUV-drivin' mommies. The seasonal menu from chef Brian Duffy has most entrees under 500 calories, a wood-fired grill, local ingredients, outdoor dining, and an eclectic wine and beer list. Desserts run under 200 calories.

Decor uses reclaimed wood flooring, recycled glass bar tops, and paperstone dividers.

It's dinner only for the first two weeks, and then lunch comes online. See menu and more photos at http://go.philly.com/harvest.

What's new

Alex Capasso has branched out from his Blackbird Dining Establishment to open the casual West Side Gravy in Collingswood's old Woolworth's store (714 Haddon Ave., 856-858-7153), which joins Nunzio's, Tortilla Press, El Sitio, and the Pop Shop on the block. Environs take a cue from the five-and-dime - it's wide open with a white-painted stamped-tin ceiling, mod paintings, and retro-'50s-style Formica tables. A few tables in the window are perched on a platform. Comfort-food menu includes sandwiches, small plates, and platters (top price: $18.50 for steak frites). Menu is at http://go.philly.com/westsidegravy.

What's coming

On Tuesday, the crew from the Pub & Kitchen opens the Diving Horse (2109 Dune Drive, Avalon, N.J., 609-368-5000), a dinner-only, seafood- and farm-centric BYOB. Its "dry bar" is stocked with stemware and mixers. Menu is at http://go.philly.com/divinghorse.

Gina Bostic and Adrienne Williams have set Tuesday as the grand opening of the Gatehouse Cafe (3300 Henry Ave., 267-297-8234), a breakfast-luncher open weekdays from 7 a.m. to 3 p.m. in a historic building on the grounds of the Falls Center, formerly the Women's Medical College of Pennsylvania. Menu will include oatmeal, bakery items, yogurts, and hot sandwiches for breakfast; soups, salads, and sandwiches for lunch. See photos at http://go.philly.com/gatehouse.

Chef chat

Dettera, arguably Ambler's hottest-looking restaurant, has a new chef: Jeffrey Power, 32, a Culinary Institute of America grad who earned his stripes as sous chef at Blackfish in Conshohocken and most recently worked at A La Maison in Ardmore after a spell at the Dolce Valley Forge Hotel and a brief return to Blackfish. Executive chef Thomas Groff, on board from the project's inception and opening a year ago, has left. Power's new lower-priced menu is due to take effect in mid-June.

The Whip Tavern, the English pub in West Marlborough, has elevated its sous chef of four years, Wyatt P. Lash Jr., to executive chef. He succeeds Jason Ziglar, who is job-hunting.

New chef at the Old City Greek resto-lounge Privé is Alpha Cisse, its former sous chef. Founding chef Peter Karapanagiotis, who got notice last fall on the Food Network show Chopped, has returned to his family's George's Place in Cape May.

Diner doings

After 23 years in Reading Terminal Market, Jack McDavid will do a full makeover at Down Home Diner this summer. Most of the construction will be done during off-hours, but the diner will close for two to three weeks while the kitchen is stripped down and restrooms are added. Down Home will add modest-priced, BYO dinner service to its breakfast-lunch complement. Eventually, McDavid hopes to get a liquor license.
