815 V Street, Washington, DC
One of the nation's most legendary venues, the 9:30 Club rests in the northwestern side of the capitol city. Prominently known for playing host to many bands during the punk-era of the late 70s and 80s, it now features live performances from artists both big and small, from all sorts of genres. The venue is owned and operated by IMP productions.
Capacity: 1200 - when they sell the place out, it gets packed as can be, so get there early if its a sold out gig you're going to.
Sound: I'm not a sound wiz, but in my opinion the sound is very good. At times it can be too loud, that's really the only thing I could make note of.
Bar/Food: There are 2 bars on the main floor, 1 bar + an espresso bar on the upper level, and a bar in the basement. The venue has a decent beer selection, and like every place it's a bit pricey. They also have a kitchen that serves a variety of sandwiches, along with 930 club chocolate cupcakes.
Staff: I've never had any problems with the staff. They're pretty comparable to staff at other music venues. They're friendly and there to help, and as long as you don't do something stupid you'll be fine. They're policies for the night (such as photo) are clearly listed throughout the venue, which is nice and informing.
Parking: The venue offer's a parking area for a fee, but every time I've been, I've been able to find parking on street (for free) with no problem. Also, the city's Metro line has a stop a couple of blocks away, so if you're staying in the city, the Metro is a feasible option.
The Neighborhood: The neighborhood isn't the prettiest - if you head towards the city, you'll find stuff to do (restaurants, bars, our nation's history), but that's really the only direction you want to travel in. There are a couple of nearby places to enjoy a meal or grab a drink before a show though.
