Burger Bar has the best gluten free burger and fries I've eaten in a restaurant, hands down. I even checked with my server to make certain the bun they served was actually gluten free. (Hint, it's made with potato flour.) To finally enjoy an amazing burger with a soft, delicious GF bun and GF steak fries after a grueling day at a work conference was absolute heaven. The fact this restaurant is part of Huber Keller's culinary universe made it even better.
Mid-afternoon, the joint was comfortably empty, and service was quite good. I had a booth all to myself, and was able to relax and watch the most recent episode of "Game of Thrones" on my iPhone via HBO GO, thanks to the free Wi-Fi at Mandalay Bay. And I enjoyed an O'Mission GF pale ale with my feast. The pickle and house-made dijon mustard were added bonuses and a nice complement to my meal.
If you're not GF, there are so many more options! I highly recommend checking out Burger Bar if you're in Las Vegas.
