Mama Cella's does a great job with traditional Italian dishes. They do an adequate job with a red sauce that is not too acidic. Their bread is wonderful, toasted with a light sprinkling of garlic.
Some of my favorites:
Spaghetti with Meat Sauce
Spinach Lasagna!!! YUMMY!
Atmosphere is small. I believe that they probably seat 50-75 people. Tile floors and small tables make you feel like you are in Mama's Kitchen. Staff is friendly, not always so speedy. Be prepared to take your time and enjoy Italy.
