After reading positive reviews here we decided to go and check it out. The guys working behind the register knew so little about what contains gluten or dairy that I didn’t trust anything that they said, and so we left.

Amazing burgers and fries, my non celiac wife also wants to return here. The staff were a little sketchy about their knowledge but the kitchen seemed to take proper precautions. Delicious sauces and almost anything can be made GF

Review
My daughter's have Celiac. I ordered two burgers, both with GF buns for take-out. I didn’t check the order before I left. One had a GF bun and one had a regular bun. Lesson learned.

Review
We like this location a little more than the Ashburn one. They have more comfortable seating, a Coke Freestyle machine, and a pay car charging station. Usually it is not as crowded as Ashburn. Daughter likes the GF burger and GF fries, and has never gotten sick after eating here.
Review
Delicious burgers and buns! Dedicated gf fryer with fabulous regular and sweet potato fries, plus several dipping sauces clearly marked gluten free.
Review
This is a new location. The food was just as good as always and I didn't get sick at all. I had a pick up order and had trouble finding the place. The owner had them cook new fries for me because the original ones were getting old. I'll definitely be back.

Really enjoyed our experience here today! I felt they took our allergy very seriously and the food was delicious! The burger was cooked perfectly and the sweet potato fries were so good too! Definitely recommend as they have quite a few things on the menu that are GF.

Tasty burger and fries! The menu was very descriptive as to what is and is not gluten free, and even lists sauces. Didn’t get sick! Food quality was good; on par with Red Robin.
