This is the best pizza I’ve ever had! I ordered a medium, but it looked like a large. From now on, I’ll only order pizza from here. The place was spacious and clean, and the staff were very professional.

Good atmosphere and overpriced pizza. We gave the food a 4 out of 5. Not very many pescatarian options, which was disappointing. Our waiter was very pleasant and upbeat. The vibes were chill. It was a bit empty in the restaurant, so we couldn’t understand why our food was taking so long. The salad was delicious, and so was my spinach artichoke dip. I would be okay if we never went back but check it out for yourself.

Enjoyed mellow mushroom. The Holy Shittakee pizza was my favorite out of all the ones I tried. Service was lovely and the atmosphere was good, hard to hear each other so that was a bit challenging.

I was really looking forward to trying this place and the taste of the pizza was really good although the crust was a bit dark but the reason for the 3 stars on the food was the amount of Italian sausage which was sparce to say the least. One slice had a total of zero sausage pieces. The service and atmosphere are fine.

Fun atmosphere. Somewhat busy for Wednesday at 2PM, but the staff was hardworking and in good spirits. The house salad was a good balance of veggies, and a good (italian?) dressing. The House Special pizza was loaded with good ingredients, had a thin crust (which people in Saint Louis prefer), with puffy outer crust. I'll be back.

My friend and I went with our girls while we were on vacationin Orlando. The girls made their own pizza, a twist on a chicken bacon and ranch... it was really good. I chose a pizza off the menu that had ham, bacon, pineapple and jalapeños and was absolutely amazing. And my friend got the veggie... but the veggies on it came out fresh not cooked so thay was weird. Other than that everything was really good tho. Our waitress was kinda slow but they were super busy. I actually can't wait to try another one closer to home.

Tried mellow mushroom for the first time today after church. My mom and I shared a small, House Works Pizza. There was plenty for both of us for lunch. We also tried the pretzel bites which were very tasty. The food was fresh and warm. The service was great, and the staff was friendly and accommodating. This pizza is the best pizza I’ve had in a very long time. The toppings tasted very fresh and they used good quality meat on the pizza. I liked the crust a lot, which reminded me of New York style pizza.

Picked up a couple pizzas here when visiting family in the area. Pick up is quick and easy, there is a separate entrance for pick up and the staff was right there to help. They show you your food before you pay to make sure it is correct, which is nice. The staff were very friendly. The pizza was good, but a little pricey. There was a good amount of toppings on each pizza and they have a variety of special pies that are unique in flavor. The best pizza we got was the mushroom specialty!
