Luigi's is a real-deal deli where the sandwiches are huge (be really hungry when you go or get two meals out of it) and incredibly tasty. I always get the Luciano Pavarotti and the hubby gets the Luigi Boy, both are excellent. The deli also has tons of other dishes from casseroles to custards. Seating is limited and the ambiance is non-existent, but you will be so enraptured by your sandwich you will not even notice.
Since I moved away I make a point to go to Luigis every time I come back. I can't even begin to describe how good they are. Just go, you are missing out!
