3 Mundos Sandwich Shop serves burgers as well. We use only the freshest lettuce, tomatoes, onions, and other vegetables to dress up our burgers, as well as premium quality cheeses and homemade Mundos dressing. The entire burger is served on a warm, toasted bun and with your choice of side. For more information about our burgers and cheeseburgers , contact 3 Mundos Sandwich Shop.
