John's Pizzeria(West 44th St.) Very good pizza, can be noisy.
We also love the Cafe Edison (in the lobby of the Edison hotel--you can enter from either 47th (back entrance) or 48th (front entrance, across from the Barrymore theater.) VERY casual, but good "diner"/Polish/Jewish food like matzo ball soup, blintzes, etc., plus the usual sandwiches, burgers, specials. Service is fast.
