Angus Jack in Springdale, Arkansas offers an amazing gluten free burger. In fact you can order any of their amazing burgers on the fantastic gluten free bun. You can check out the pictures on their Facebook page. They also offer great fresh cut fries and sweet potato fries.
I talked to the owner and he explained that they have a designated bun toaster, fryer and prep area that services their gluten free menu so there is no risk of cross contamination.
They also offer a wide range of speciality drinks and shakes that are all gluten free. I think I counted over 30 flavor combinations.
The owner also mentioned that they are planning on adding fried onion straws, fried pickles and fried mushrooms that will be made with rice flour.
If you live anywhere close to Springdale, Arkansas, I would for sure check this place out.
