The #1 problem seems to be that they insist on toasting all the damned buns on their grill. Thus, even the meat can be cross-contaminated even if you don't order a bun. The Udi's buns are fine of course, except those also get toasted on the same grill as everything else. The other issue is it depends which manager is on duty how careful or not they are. Most of the cook staff are workers with little training.
We have eaten here quite a few times, but occasionally been noticably contaminated. The order-taking staff are usually very good about GF and will mark the order as "gluten allergy" but that doesn't matter a lot with the above problems.
