Oo, I liked this bar. We went to check it out last night, and it's just about the right size, with lots of different seating options and places to hide out (if so inclined). Everyone was incredibly friendly, the bartender was nice as hell, and the drinks were good. We might wish for a more adventurous selection of beers on tap, but I get that Petra's isn't really a beer bar.
For a Saturday karaoke night, it was actually a little dead... there were enough people there, but the karaoke wasn't particularly hopping. Still, I plan on going back again soon, maybe for trivia night... I love a good trivia, and $6 pitchers ain't nothing to sneeze at.
Glad this place exists.
