Had a think crust slice at Zachary's on Solano the other day and was kind of shocked at how bad the crust was. It tasted like the crust you get on a bad frozen pizza--hard, thick, no chewyness, really boring. The cheese and tomatoes on top were great (I ordered a marghrita), but I couldn't get past the crust. Little Star, which opened at the other end of Solano last year, is way better, as are any number of other pizza options around the Bay Area.
