This is our family go-to for burgers. Love the rotating burger of the month. Food is consistently good. My wife is gluten free and they take good care to make sure there's little to no cross contamination. She's never had an issue eating here.
Use their app for convenience but if you are ordering gluten free, be careful no to select gluten-free bun AND gluten-free allergy. You'll be double charged. I just select "gluten-free allergy" and the bun is an option. Though my wife usually orders bunless.
