Solo diner before concert at Time Square
Just recommended St. Andrews on 44th between B'way & 6th to my husband for a pre-concert dinner with a crowd of 4 guys about the same age. They thought it was a perfect precursor to the concert they went to, so maybe it will fit the bill for you, too.
St. Andrews has a nicer sit-down dinner menu, but you could definitely hit your price range with the pub menu. They have a great atmosphere and great bar, too!
