Bolstered by an influx of younger residents, downtown Philadelphia is gradually shedding its reputation as a town that rolls up the sidewalks early.

This is good news for crowds of delegates, media reps, and other Democratic National Convention-goers prowling for food after convention business winds down. (Drinks will be plentiful late, as bars may serve till 2, 3, or 4 a.m., depending on their authority.)

I've put together this map of 70-plus bar/restaurants - all in Center City, South Philadelphia (on the way back up from the Wells Fargo Center), or a short cab ride away - whose kitchens will be open after 11 p.m. during the convention. It's a sampling of what's out there and by no means all-inclusive.

Most serve till 1 a.m.  Chinatown tends to run very late, till 3 or 4 a.m. Center City has only a few 24-hour diners: Little Pete's (219 S. 17th St.) and Midtown III (28 S. 18th St.) in Rittenhouse, and South Street (140 South St.) in Queen Village. If all else fails, there's a 24-hour Wawa convenience store at Broad and Walnut Streets, which has indoor seating.

A note about breakfast:

Weekday breakfast in the heart of Center City is not so easy to find, beyond Panera, Le Pain Quotidien, and Corner Bakery, or the hotel restaurants.

A few ideas: Jean's Cafe, a budget-friendly hole-in-the-wall at 1334 Walnut St., starts cracking eggs at 6 a.m. Con Murphy's, the Irish pub at 17th Street and the Parkway, opens at 6:30 a.m. The casual MilkBoy at 11th and Chestnut Streets, popular with staff at Thomas Jefferson University Hospital across the street, opens at 7 a.m. Jones, the diner-ish bistro at Seventh and Chestnut Streets, opens at 7 a.m. for the DNC. There's IHOP at 1320 Walnut St. Many vendors at the city's best all-around food destination, Reading Terminal Market (12th and Filbert Streets), are open at 7 a.m. The elegant Parc at 18th and Locust Streets opens at 7:30 a.m. The no-nonsense Green Eggs Cafe at 212 S. 13th St. opens at 8 a.m.
