Restaurateurs/actors Rob McElhenney and Kaitlin Olson will be back in Philly to shoot exteriors for season seven of It's Always Sunny in Philadelphia. They're expected to look in on their investment: Mac's Tavern (226 Market St.), which they own with a bunch of McElhenney's buddies from St. Joseph's Prep. The Fx shooting, which will include series costars Danny DeVito, Glenn Howerton, and Charlie Day, will be done June 23, 24, 27, 28, so plan your visits accordingly. Meanwhile, Mac's has stepped up its menu, adding a half-pound, 12-inch chili cheese dog, "Sweet D's" roast beef and cheese on a Philly Pretzel Factory roll, shrimp gazpacho, and a B.L.A.T. sandwich (thick cut, pepper crusted, maple bacon, avocado and tomato).

The University City District will host "Sustainable Saturdays: The West Philadelphia Local Food Series" with tours, urban farming activities, and beer and food events. They'll run on the third Saturdays, June through September. Themes: June 18 (Grow It Yourself), July 16 (From Farm to Table), Aug. 20 (From Seed to Compost), Sept. 17 (Preserving the Harvest). Details here.

Center City Sips, the happy-hour promo, returns on Wednesdays from June 1 through Aug. 31. From 5 to 7 p.m., 85 bars offer $4 cocktails, $3 wines, $2 beers, and half-priced appetizers. Some will offer a 15 percent dinner discount after 7 p.m. Details here.

Two Shore points -- one good, one painful to watch:

  • The good one is, which just expanded its happy-hour coverage to the New Jersey Shore towns. (or is a database of events and drink specials.

  • The one that hurts: White House, the Atlantic City sub destination, has opened a stand inside Trump Taj Mahal -- a mile away from its Arctic Avenue landmark location. It's next to, sigh, a Sbarro and Berriyo.
