Toppings (sausage and mushroom) were few and far between, especially the mushrooms which were almost nonexistent. Toppings, sauce, and cheese came only half-way to the edge, just dough after that. Top was way over-browned to the point where the cheese was disagreeably chewy. And I'm not sure if this was meant to be a thin-crust or a deep-dish pizza because it was both: thin in the middle half and three times thicker in parts of the outer half. Obviously whoever prepared this has no clue to how to do it properly. The ONLY good thing I can say about this mess is the dough itself was fresh and had a good texture. It wasn't just one. We were a group of 5 and ordered 3 pizzas. Everybody agreed they were bad. They should be ashamed to serve these. Didn't anybody notice leaving the kitchen they were unservable? So I would never consider here for take-out. But we were here for trivia night so maybe I'd try again to have something to eat while playing? But next time if they come out like that I'd be refusing delivery and demanding a new one - that's for sure. As far as the trivia, I might not return for that either. The room was very loud from the crowd, and the announcer's microphone never did work properly so it was very hard to hear. And, knowing how many good wines and beers they sell in the general store on the first floor, it is painful to have a choice of just 5 very generic wines upstairs. Why can't they offer all the wines from downstairs, with a reasonable mark-up for restaurant purchase of course?

The employees have that blank Gen Z stare. It's insufferable. Good to know zombies are being hired though. I don't want to have the red carpet rolled out when checking out, but a general "hello" and half smile isn't a ton to ask? They seem to think that the registers are their school lockers as they stand around, not bagging anything, chatting about their brocoli hair. This place is good in a pinch, but too expensive for the selection and quality and atmosphere.

Will visit the other two gas stations on the way into Groton instead which have bathrooms for their customers. Price of gas is not the best in town. In fact it is at least third consistently.

No more visiting for here with the kids on Saturday morning before sports because of the bathroom situation. Don't want to get stuck with the kids needing to go to the bathroom.
