This place makes a mean sandwich and, even though it's in the heart of the loop, it won't hurt your wallet. My friend Aviva shows up at my house sometimes with a present for me. It's always a sandwich from Fontano's.
The one time I was in the store itself, the people behind the counter were yelling at each other amiably, and the woman who seemed to be in charge brewed us a fresh pot of coffee so we could sit and wait for our friend. She didn't charge us for the coffee and didn't have a problem with us sitting there for 20 minutes. My sub was delicious.
