It looks like you only saw what you wanted to see, and didn't really pay attention.
I've complained about corporate creep on Mill for years now. Even so, 9 out of 10 businesses in the Mill Ave. district are still either locally owned, or part of corporations based locally, such as Coldstone, Z-Gallerie, Coffee Plantation, P.F. Changs and Buffalo Exchange. Other chain-based businesses in the district represent early expansion outside their territory. For example, the Gordon Biersch was the first one established outside California, and the Urban Outfitters was the first one west of the Mississippi.
