DiPaolo's is a very good restaurant that attracts people from all over who brave the location, (not the best neighborhood) to eat here. I'm partial to DiPaolos because the 2 best sandwiches I've ever eaten, the grilled vegetable sandwich and the Big Mikes Special, are served here.
I've eaten lunch here, the lunch buffet here and the dinner here often. I'll confine my comments to dinner, since I'm assuming only locals come during lunch. Dinners are pricey, but 90% of the time you walk out with a doggie bag. The antipasto that comes before the meal is top shelf, and if it's on the menu, it's pretty good. HOWEVER, the service here ranges from below average to indifferent. They are certainly in no rush to get you out of there, and if you're in and out in less than an hour and a half you've done well.
Overall, this is a very good place to eat. As people have mentioned, it's locally owned and they care about the food that comes out of the kitchen. If you have the time, I highly recommend it.
