Try the Spartan Sandwich. (From the Modern Cafe website) Steak, Gyro meat, Provolone & Feta cheese, onions, tomato slices, special steak seasoning & dressing topped with tzatziki sauce on a 6" hoagie.
So good.
The bar itself is OK. Not a lot of ambiance, but a great neighborhood place. I no longer live in Pittsburgh, but used to spend a bit of time at the Modern Cafe when I lived in the neighborhood.
