Aces is a neighborhood bar (though not my neighborhood bar, sadly) that caters to local clientele. They have amazing drink specials and very colorful service, so if you're looking for something laid back and a strong drink for a good price - check it out.
Thursday nights are Team Trivia nights so don't expect speedy service if you're not prepared to stay the two hours for trivia.
Also, throughout the summer they're known to throw FREE Crawfish/Seafood boils about once a month (usually a Sunday afternoon).
Dress Code: Casual - these are locals.
Little Five is a good place to see an interesting cross-section of people. There are artsy hipsters as well as the preppy spill-over from the VA-Highlands crowd. Nobody is out of place here. Lots of good eats (Corner Tavern, Vortex, Porter, El Myr) and interesting drinking holes (please see any of the aforementioned good eats for interesting drinking holes).
Very colorful Halloween parade every year (please see picture).
Dress Code: Nothing is off limits, but don't overdress.
This place is very unique. A must see to appreciate. It is an eccletic group who usually hang here. Go to the Vortex.
