The pizza here is good. The many crazy toppings and specialty pizzas they have add lots of variety to the standard fare. I recently split a conqueror (XL) with my roommate and was able to feed myself for a whole day for $7.50.
However, their customer service leaves something to be desired as many other reviewers have mentioned. I have never had any huge problems myself, but based on their overall attitude, I assume the 1-star reviewers are not alone in their bad experiences. In general, if you are someone who is pretty easy-going and isn't easily upset by poor service or are willing to sacrifice great service to save some money, then I definitely recommend it. They have online ordering and menus as well.
