I like Hough's! I think it's one of the best parts of an otherwise quiet and relatively boring neighborhood (sorry, Greenfield). My friends and I used to go there every Tuesday for trivia! The games are fun, and the girls who usually run it are very nice. Sometimes it gets really loud and it's hard to hear, but sometimes different breweries will come and give out prizes and offer tastings. It's pretty fun.
The beer selection is insane, way better than any other bar I've been to in the area. They offer a couple of different sizes, so you can order small little taster sizes if you want to try a few different kinds. I'm not much of an adventurous spirit when it comes to beer, but I do appreciate the variety of ciders they have included! :) I haven't found anything on the food menu though that has impressed me. Nothing I've had has tasted bad or anything, but it's pretty bland and generic and nothing to write home about.
Hough's is a nice place to go and watch a game. I'ts pretty big for Pittsburgh standards, and there are plenty of tables and TVs available.
Just go seat yourself. Sometimes it takes a server awhile to get to you for some reason, but on the up side, that just gives you more time to look over the expansive beer menu.
