The Moose is a very interesting place. Upon arriving don't' let the big scary bouncer dude that scans your idea back you out from entering. I've gone in this place dressed like a total prep to a total metal head/punker and have never had a problem with anybody in there. Lots of horror pictures and scary masks fill the walls and usually there is rock, metal, electro, or industrial playing on the juke box. The people drinking there are friendly and come from all different kinds of scenes around the burgh area. The bar tenders are fast, nice, and courteous, and I have never had a problem waiting a long time for a drink. They have your basic beers on tap and a wide variety of bottles that can keep your taste buds entertained if your are bold enough to try something new.
They do have a food menu, but I've yet to try any of their dishes yet.
Make your way upstairs and you can usually find some type of rock/metal/punk band rocking out to a small but hungry crowd. There is also another bar up stairs and some old school video games that are always entertaining to play and bring back good memories of being a child.
The bathrooms here are a little odd haha. Since I am a guy I can only comment on the guys room and its very small and crammed. Its painted dark green with stickers, and fliers and writing covering the wall. It can be a little intimidating at first but its cool when your pissing, you can read the crazy shit that people have written over the years.
This is a sweet place to drink and every journey I make to the south side I make sure to at least have a beer in here weather the place is crowded or not. I like the atmosphere and the big video board they have which is always playing something cool that goes along with the music blasting, and recently they have been putting the Penguins games on their big screen projector so that's a plus! Definitely go into the Moose. I'll keep going back to it too so maybe ill see yinz there!
