Papa Sammy's is the real deal. My wife and I stopped in for a late lunch. There was a family of four that came in right after us, but other than that, the place was empty.
First thing I want to comment on is the cleanliness. I don't have super-high expectations when I go into independent, hole-in-the-wall type places like this. Papa Sammy's very pleasantly subverted my expectations. Both the dining area and the part of the kitchen I could see were spotless.
First, we tried some garlic knots. They were excellent. Perfectly baked, crusty on the outside and tender on the inside, with garlic butter and parm. There was a small pool of garlic butter at the bottom of the basket, which for gluttons like myself was a great dipping option.
I got the stromboli, hold the ham and add mushrooms. My wife got the 8" pizza with pineapple and banana peppers. They came out in a very reasonable amount of time. The stromboli was great, with an excellent ratio of cheese to filling. Shortly after dropping off our food, the cashier girl dropped off a little ramekin of what turned out to be a VERY spicy habanero dipping sauce that I hadn't asked for. Turns out the other table had requested it and it got dropped off at our table by mistake. No harm, no foul; as a lover of all things spicy, I forwent the marinara and instead used that as my dipping sauce. It was fantastic and had me sweating in short order (that's a good thing).
I tried a bite of my wife's pizza and it was tasty, though pineapple and banana peppers are basically the opposite of what I like on my pizza. She enjoyed it very much, and that's what matters.
This place really impressed us. We're moving very close by very soon, and I have no doubt Papa Sammy's will make it into our regular rotation.
