We went on a Thursday night, which happened to be open mike night. It was packed! We barely found a spot at the bar. The place itself is quite large with lots of different 'areas' to hang out in. The open mike night was a lot of fun and I'm glad we happened upon it. Even our bartender got up to sing and he was awesome... probably the most talented of all the brave souls playing that night!
Drinks are really quite cheap and it wasn't even happy hour time. Also every time a fire truck goes by (its adjacent to the fire department) drinks are $1 for fifteen minutes! Pretty cool and appropriate special that they have enacted! The wings were actually quite good... at least crispy and not completely lathered in sauce.
Definitely more of a dive bar with random posters etc all over the walls and no frills to speak of but its also not that ghetto or intimidating. It definitely suites a younger crowd and has bands playing there regularly.
Overall a really nice and necessary alternative to Mill Ave.... Tempe needs more bars like this!
