We LOVE this place and eat here everytime we come. I wish I could say they are 100% safe but be wary. We've had the Meaty, Pepperoni & Olives, and the 7 Cheese pizzas with zero problems.
Unfortunately I believe their grilled chicken on the Pollo Bella is cross contaminated (possibly cooked on the same grill as something else?) I felt queasy after eating it last night, and have been having really bad symptoms all day long.
The staff is knowledgeable but I would stick with the veggies and cured meats (sausage, pepperoni, etc). The crust is really yummy and the cheese is divine. Just be careful! It's so good it's worth the risk!
