I have only been to this location once, but also Dana Park and Chandler Fashion Center. The flavors aren't all that great IMO and once got sick after they recently changed out the flavors in the machines. All gf options are listed on machines, which is great. However, I doubt they clean the machines between flavor changes. chance of cc. also, yumberri on tatum and cactus has much better gf labeled flavors. however, I do not know if they clean machines in between flavor swaps as well.
