My new favorite pizza place. Pizza is delicious and the cinna bites are a must!

I went in for lunch. I got the chicken Alfredo. The service was good. Salad was good. The pasta came out in a aluminum foil tray and it was apparent that all they did was put the pasta from a freezer in the oven and cook it. If I'm paying 15 dollars for pasta I expect a actual plate of pasta. I've had better at fazolis or pizza hut in a truck stop.

All you can eat pizza, salad, fried chicken, mashed potatoes and gravy, meatloaf, etc. Food was fresh and hot.

★★☆☆☆ 2.0 Cory Bellings · Jan 2025

Stopped Saturday. Service was slow for only having 2 tables. Ordered 2 155 pan pizzas and got what appeared to be 2 medium original pizzas that were lacking toppings and flavor. At around $24 a pizza, I would have thought it would have filled our family of 4, but we left still hungry. Took about 1 /1/2 hours to get our food and eat. May have been faster if the lady in the kitchen would have put her vape down.

★☆☆☆☆ 1.0 Erin Rowan · Jul 2023

We were promptly seated at a dirty table and got drinks. We wait an hour for our pizzas and only time server was at our table was when we waved for his attention so we could get refills on drinks. During this, we were hearing someone with takeout asking if their order was forgotten because it was taking so long. Pizza tasted ok, but we got gluten-free and member of our party got sick so there was definitely cross-contamination. All around poor experience.
