Town is a restaurant in San Carlos that features large lunch and dinner menus with steaks, chops, seafood, organic produce, cocktails, and wines. They have special gluten free menus for lunch, dinner, and brunch (Saturday and Sunday), which can be viewed online on their menus page: http://www.townsc.com/menus.html
All of these menus have vast options for those who have gluten intolerance or Celiac Disease. They also accommodate vegetarian diners, though most of their meals are meat-based. Since the kitchen is not 100% gluten free, the risk of cross contamination is possible, so be sure to let your server know the extent of your intolerance.
