Oh my goodness where do I start. Came over here to get the one session the other day for $10. I got a slice of pizza that was so big. I ate it twice and a salad. Came back this week. Had to try the Gabagool. I made the right choice, So good! Got Frank Sinatra playing in the background, Definitely A real Italian family made these recipe recipes. The homemade sauce is to die for. You can even get a quart of their sauce, premade raviolis, or fresh pizza dough to go.

I decided to try this tonight instead of going with a chain pizza spot. Straight to the point, it was ok. Im not a big fan of the sauce but the crust is good tho a bit chewy for my liking. The garlic bread was cool and the toasted ravioli were good. I had a little bit longer wait than anticipated but it was OK bc the atmosphere is nice and welcoming and the staff are very nice and professional. Not sure if i’d go back for pizza. I’d maybe give it another go for other menu items tho

Visited for the first time today. Cutest little spot, and whoever served me (I think it was the owner) was very kind, professional and thankful. I got the chicken parm on cheesy garlic bread and a side of jumbo toasted ravioli. The sauce for both was phenomenal. Best t-ravs I’ve had in a LONG time as well.
I personally think the chicken was missing some seasoning. It didn’t have a big Italian flavor pop to me, but it was still great. I don’t think the bread worked with it, but I bet it’s great with other sandwiches. I can’t wait to come back and try again!

Located in a historic railroad building in Old Town Florissant, this is a great new addition to the St. Louis area pizza scene. Pizza was great, we then walked across the street to get some Fritz’s Frozen Custard, and then crossed the road to get some Old Town Donuts. Great combination.

Italian Beef sandwich was amazing. Pizza is on the thick crust side, but not crazy thick. Definitely will be back to try other items.

The pizza was amazing. We ordered the supreme, and it had the right amount of toppings. The crust was toasty just the way we like it, and the staff was friendly. It will definitely be our first spot to visit when we return to Missouri.
