Grandpa's must be experienced to be appreciated. At first you'll see that this family business is for real, and they're friendly. As they continue to see you, they will ask specific questions about you because they remember you. They care about you.
That's the personal side. Forget that!, because the food is the reason to keep going back. You will. Their Sicilian is THE finest I have had outside of NYC. I have had a sampling of most of their menu - the pizza is the reason I keep going back. You can do a lot worse for more money.
