On my initial visit to Gandolfo's, my first impression was, "Holy menu size, Batman!!" There are so many sandwich options that it is a bit overwhelming. The sandwiches are listed by Hot and Cold. You can get just about any combination of toppings, meats, sauce you want. I've never had a bad sandwich at Gandolfo's.
I have eaten here many times, and on about half the visits, the owner came to our table to visit and make sure everything was to our liking. It wasn't a token visit either. I'm not sure how to explain it, but I could tell the interest was genuine. I felt very welcome, rather than put upon or intruded upon.
Gandolfo's is not a formal restaurant, but it is not "fast-food" either. It's somewhere between the two. It's worth you checking out if you have never been there.
