Double Rainbow is more than just an ice cream shop. Yes, it features ice cream choices and hot fudge sundaes galore, but also espresso, chocolate, tea, desserts and smoothies. For a light meal, try a fresh salad or sandwich. Owner Steve Messina, former mayor of Benicia, is especially proud of his "gourmet, boutique" sandwiches, which are made of roast beef, turkey or just about anything a customer may desire.
