🔗 Burger 21 is a chain. We reviewed the Charlotte, NC location — dedicated fryers and prep areas often differ store to store, so confirm these details at the location you visit.
Always a go to spot for us, we have been coming here for years and never had a problem. Though the kitchen is shared, they take good care and even add stickers to designate gluten free items
