FYI, Anna's is now carryout and delivery only.
Tried it for the first time today and was very impressed. Great light, crispy crust and while some pizzas go for the "spice bomb in your mouth" approach Anna's has a more subtle flavor, which seems to be pretty common from around here and south to Rockford. If you've been to Jim's in Janesville it's similar, but less sweet.
Yes, Anna's does use canned mushrooms but there was a time when just about EVERY pizza joint in this part of the country used them, and they're what a lot of us remember and love.
