Came here on a weekend. It was pretty quiet. I ordered a bacon, chicken ranch slice for around five to six dollars and it was pretty good.
Overall, a decent slice. Also, if you go on the Yelp page for this place, there are a ton of one to two star reviews, not for the food, but because a lot of people hate the boss here. He’s apparently really rude and angry all the time. I didn’t see any of that. My time here was quiet.
