Went here with my wife and daughter during a slow period on a Saturday night. The service was okay, but our waitress was a bit awkward. Friendly, but awkward. The food was okay, but VERY greasy in my opinion. I've definitely had better pizza and garlic bread with cheese at other places.
I always judge a restaurant by how it makes me feel afterward, and I didn't feel too great after eating at Sal's. I had a sick feeling in my stomach as soon as we left, and I have a feeling that it was because of all the grease.
