Houston's best kept secret when it comes to pizzerias. Belive me I know. We are know for our thousands of restaurants. Even out of the big 3 chains (Dominos, Papa Johns, Pizza Hut) its my personal favorite place to order pizza from. They are a chain pizza place in Houston with about 12 locations. Sicily's pizza cooks on a slab stone, in an old-fashioned hearth oven, and they use fresh Wisconsin cheese. Their pizza has very little grease compared to most places, and their pizzas taste alot more fresh and of better quality. Not to mention they have AWESOME chicken wings (10-100) in various delicious flavors. They also have delicious traditional pastas and big decent sized salads. You get your money's worth.
On the down side, you are best to call in your order or go to the restaurant personally to order, because if you order on-line you are taking a gamble (one time they didnt even show up after I ordered!). Still...delivery service aside, in my experience Sicily's has the best tasting affordable pizza in Houston.
