Monkey Burger: 5350 E. Broadway, 514-9797. and 47 N. Sixth Ave. 624-4416. This homespun chain has a dozen signature burgers to choose from at two locations, one in the Williams Center and the other across from the Ronstadt Transit Center, downtown. Both locations work with Angus beef and make many of the sauces and toppings for the burgers in-house. Spokesman Mark Volner said the local chain's top three burgers are The Monkey, with roasted poblano peppers, sauteed mushrooms, onions, lettuce, tomato, bacon and two types of cheeses; the Smoked Cheddar and Bacon burger with shredded lettuce, diced tomato, onion and a garlic herb mayo; and the Sonora burger, which comes with Chihuahua cheese, shredded cabbage, diced bacon and an avocado salsa topping. Monkey Burger regular Carrie Fox, 31, prefers The Plymouth, the restaurant's turkey burger, with smoked mozzarella cheese, shredded lettuce, sun-dried tomatoes and an avocado pesto. "I love turkey burgers in general, but their burger is so juicy," she said. Choices range from $7.50 to $9.50.
