I had an awesome thin crust pizza from Wana Pizza (as in Wanatah) last night. It was thin but not too thin, with a hint of garlic butter on the crust. The sauce was great as well and it had a think layer of cheese. I wasn't too fond of the sausage, but I don't like most pizza sausage. A flier on the counter said they are having customer appreciation day the 27th and 28th - a large one topping for $5. I think its only at their second location in valpo though.
Just to warn you, their regular crust is sort of like a breadstick. I think its a little too dense, but my friend thinks its really good. Also, the place is really chowhoundish. The one in valpo was previously occupied by little caesars, so there is only two tables.
