I don't know what the middle flavour was; I just kind of pointed at it. The pizza isn't bad. Compared to Pizza Pizza, it's gourmet. The crust isn't super thick, but it holds up okay. It also isn't bland. I think the white sauce on the middle slice tasted like ranch dressing.
Would I return? Yup. It's cheap and fast. It's hard to find a complete meal for $5 these days, but they managed to make it work.
Total damage: $5 for three slices and a pop.
