I'm surprised that no one made the comment that Frontera Grille & Topolobampo are under one roof, the latter being the more upscale of the two. I'm not a big fan of Mexican food but wouldn't dream of dining in Chicago without stopping at Rick Bayliss' (no relation) restaurant(s). The food bears no resemblance to any Mexican meal you've eaten before. If the garlic bread pudding is on the menu as a side dish, order it. And please report back on wherever you dine.
