Review of Red Robin

Waiter had trouble locating the "allergy notebook". Gluten free indicated one could order some burgers or grilled chicken dishes without a bun or they will begrudgingly serve with lettuce wrap. Burger taste like something had been burned on the grill & the chicken was rubbery. Waiter was borderline rude as if he didn't have time for anyone that required a little extra effort. We won't be back !!!
