Peanutz is a perfectly good neighborhood bar on East Ohio Street. Their beer selection is adequate (basically all the American macro lagers, plus a few of the more widely-known craft beers, like Sierra Nevada), and their bar is stocked with the full gamut of booze (except ouzo). Trish, the bartender, is a fantastic bartender with a hilariously sharp tongue.
I haven't tried very many of the menu items, except for the chicken wings, which are a house specialty. Everyone recommends the Four-Dip sauce, which is pretty good. The Cajun rub is good too.
Decor-wise, Peanutz is focused largely on Pittsburgh sports -- there are two large display cases with all sorts of sports memorabilia. There's a handsome wooden bar in the front room, and a dining room off to the side.
