I've been coming here for my Polish food fix for years. Pretty much everything on the polish part of the menu is good. Give me those perogies and the stuffed cabbage. Both are top notch. If you don't know what to get I suggest you try one of the Polish Platters which gives you a little portion of everything so you can find out what you like. Perogies are half off from 5-7 everyday! I love to take my non-pittsburgh / non-polish friends here.
Inside is pretty grungy, but in a good way. BBT even comes with one of those dungeon-like basement dive bar bathrooms. If the bar area is too grimy for your tastes, then feel free to take your food out to the deck area which is a great place to chill on warm summer nights.
The owner is a Central Catholic guy, so mad props to that. In all seriousness he is a really nice guy and will chat with you for hours if you let him.
Give BBT some credit for carrying East End Brewery on tap too!
