Eddie Cuéllar created a terrific following for his fancy burgers at the trendy joint he built in his sleepy hometown of Alamo. Now he has opened a McAllen outpost, serving the same hand-ground Angus chuck on airy homemade buns. Options include the Sexy Mexi, featuring a chorizo patty, crema, avocado, and jalapeño, and the namesake Tower Burger, with a sunny-side-up egg, crunchy onion strings, and special sauce. The house-made Idaho potato fries are the real deal.
