We ate at the Rainforest Cafe in Grapevine, because my nephew is visiting and the Rainforest Cafe is near the Great Wolf Lodge, where we were staying the night.
I have not had a lot of luck with the Rainforest Cafes (in various locations) in the past, but they did a decent job this time. The manager came out with a big Book O' Allergens. A downside was that he did not have a list of items that ARE gluten free, but rather a list of all the things the restaurant serves and what allergens that item contains. So I had to say things like "what about the mashed potatoes" and then he would hunt through the book looking for the entry on mashed potatoes in order to answer the question. I had a satisfying meal -- rotisserie chicken, mashed potatoes, and grilled veggies. I still wouldn't venture here if I wasn't desperate to please a young child, but they do have food available that is safe for someone on a GF diet.
