By far the greatest pizza in Waltham. Sabatinos is a casual restaurant with a thin-crust pizza that is wonderful. Staff is very friendly, and service is very quick. Try their famous Al Pacino pizza, with prosciutto, peppers, and various cheeses. Delicious!
Waltham has plenty of pizza places around, but Sabatino's is the real thing--authentic Italian pizza, at a great price. Check out the nightly specials to get the best deals.
