The South Rim has a wide selection of choices when you are ready for something to eat. You can choose from a simple grab and go option at the numerous cafes in both the Bright Angel Visitor Center and Market Plaza or you can purchase groceries or stop at the deli at the Canyon Village Marketplace. Maswik cafeteria, located in the Maswik Lodge, is a great way to feed a family with both cafeteria style service and a pizza pub. There are more formal sit down restaurants available as well. The Arizona room in the Bright Angel Lodge is available for lunch and dinner and the Bright Angel Restaurant is open daily.
