Of the two choices in Grass Lake, Big O's is the best. Their pizza sauce is just right. I don't like a lot of sauce so that all the toppings slide off when I pick up a piece of pizza. The best is their breads. They have cheesy, garlic and bacon ranch. All three are great and make a great addition to a party. My kids also love their pizza over the other place in town. Prices are reasonable and they do run pretty good specials. Delivery is only $1. They do deliver quite a ways out of the village. With gas prices being so high, remember to tip the driver. My personal favorite is the barbecue chicken pizza. They also have a good Philly steak pizza. During the week they offer a lunch buffet too.
