Bruni gives Mesa Grill 1 star but the review was pretty scathing. I agree with just about everything he says and I've often contended that the food is no longer innovative or exciting and that the flavors can be found at many chain restaurants and Bruni seems to agree as exemplified by this passage, "At the same time the margin for clumsiness at Mesa Grill is narrower than ever. The restaurant can no longer lean on novelty; its Southwestern swirl of peppery rubs and smoky glazes, of tropical sweetness and desert fire, has been popularized to the point of cliché. It informed the menus of Chi-Chi’s, Chili’s and Chipotle."
