Over 325 D.C. bars can serve until 4am this July 4 weekend

Get ready to party late for America's birthday: More than 325 D.C. bars, restaurants and clubs can serve booze until 4am over July 4 weekend.

Why it matters: National Mall fireworks may not start until 11pm — and between the heat and the no-cooler rules, a cold drink afterward might sound pretty good.

The big picture: D.C.'s "extended hours" program lets approved locations serve alcohol until 4am — and stay open 24 hours — for holidays and major events.

For Independence Day weekend, participating businesses can keep the party going from Thursday through Sunday.

Over 325 businesses made the list, from buzzy restaurants like Le Diplomate and Barbouzard to neighborhood faves like Martin's Tavern and Tune Inn, plus late-night clubs including Echostage and Soundcheck.

Yes, but: Just because a spot can pour until 4am doesn't mean it will.

Many decide based on demand, so check before you head out — assuming you're still making plans at 3am.
