Tessaro's is a pittsburgh legend in my eyes as I've been going there consistantly since I was 13-14. I see some of the reviews here of people not getting burgers and complaining, that should be enough for any perspective diners to obviously only get burgers at Tessaro's.
Everything else is hit or miss but the burgers are amazing, woof fire grille, filet on the inside of the ground meat and this burger is heaven. The service can be a little shaky at times and the woman who seats you can be a litttle grumpy, but its all worth it for the burgers. My fav is the bleu cheese burger with creamy bleu cheese.
