I always forget and tell people that Pomeroy's is on Central. I think it must just be that cool - I'm trying to pull it closer to the other really good places to go. It is, in fact, on 7th St. and if you tie it on a little tight, the grocery behind is, in fact, open late.
It looks like a bar that should have a few regular bar flies and music that screeches to a halt when someone new walks in. And by that, I mean it's the most endearingly divey of bars.
There's shuffleboard, just give your id to the bartender in return for the pucks. There's pool, but you pay quarters for that. The juke box is electronic and you should expect that you're gonna hear Def Leppard at least once during the night. The regulars will help you learn darts, the food is griddle-fare and the guys behind the bar are always good for a chat or to grab you a pint.
Pomeroy's should definitely be on your rotation of places to be in Phoenix.
