Sorry, can't help with Soy, but I can with gluten free (I'm Celiac).
Rainforest can do GF, the food is good but the choices are limited. However they have a killer GF cheesecake. Non-GF BFF orders it every time!
I've never eaten there, but I understand that Tortilla Jo's and Jazz Kitchen can accommodate GF. I think House of Blues can, but I'm not sure.
