My grandmother had the American burger and loved it. I am vegan, though, and I wanted a burger as well but there were no great options for me. I had a portobello wrap with a salad (I was informed that the veggie patty is NOT vegan and neither are any of the buns). The wrap was good but I was really just in the mood for a vegan burger. The server who took my order was amazing. Most people wouldn't care about helping me stick to my diet but she pointed me towards an entirely vegan friendly meal and I was very grateful. It would be nice if they could use vegan patties and have a vegan bun option available for those of us who want to join our meat eating families for a meal out.
Edit: Thanks for the response! I'll be back as soon as you guys have the vegan buns!
