GROSS JUST GROSS! Inedible! Made My Husband take it outside to throw out the almost entire pie! Still looking for a decent pizza in The Mission Viejo Area. Someone who has actually been to Italy.

This take out pizza is very heavily loaded. Our cheese, tomato and sausage pizza was more like a knife and fork pie than pizza. Bland,greasy and not my style but very full and filling. They offer a lot of food at a reasonable price.

My family (now grown) have been going to this little "hole in the wall" pizza place since 1978 when we moved into Mission Viejo. The pizza continue to have the same great high standard as always. Unbelievable pizza. When my adult kids come me back to visit us they always want to have Big O Pizza. I'm sure theyll be... More

Can't tell you how many time I've ordered great pizza from the "O". I have painted my house, had people over for porker, welcomed my new born son to the world eating the "O". You always know what you are going to get when you order a pizza from this place.

Big O to Go loads the toppings on to make one of the best pizzas I've ever had. No seating, just order and pick up. Choose what you want on it and they'll make it to order.

I have only been here for the sandwich and they are always very good, the Italian sub and meatball sub are excellent I will try their pizza next as I am sure it is very good too.

Has been in the same location forever--through good times and bad. Most customers find out about Big O by word of mouth recommendations from neighbors (that's how we first found it). Which possibly tells you all you need to know. Good pizza; good toppings. They also serve other items but pizza is what they're known for. Don't mistake this for... More
