Costello's Pizzeria & Subs — Restaurant in Florissant

Opened Jan 31st in a small building but has a few tables to sit and dine in. It's mainly a place to pickup order and take home to eat. Be patient and plan ahead to order during dinner times. With it being new and small, your wait times during peak times will be over an hour wait. Definitely worth the wait.

Called in a Order on a Friday at 4:30-45p for a pizza and sandwich. They gave us a 6p ready time. Order ended up being ready by 6:15p No big deal bc we anticipated the wait time.

The pizza was great and so are the sandwiches I've ate in the 2 days I been there. Prices are pretty good for the amount of food you get. Might be my Saturday go to...

My husband and I dined there for the second time last week. The food was delicious. Our first visit, we had sandwiches. My husband ordered the meatball while I had the Italian beef. Both were perfect! Extremely flavorful and packed full of meat! Our second visit to Costello's we shared a pizza. It was truly a very delicious... true Italian style pizza! We ordered a pepperoni and sausage and you could tell the sausage was homemade. Extremely flavorful sauce, tons of meat and cheese and great crust! The owners are personable and polite! We really enjoyed our dining experience and will definately be...

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...
