There are a number of these restaurants throughout California and Arizona, so I have not listed one specific address since I have visited almost all of them in Ventura County. The Habit has never failed me. What impresses me beyond their consistently delicious and fresh food is their attention to customer service. The employees at each restaurant I have visited clean tables, take away trays from customers who have completed their meals, and ask if the service has been satisfactory. The onion rings and milkshakes alone are worth a stop!
