Have been on a mission for years trying to find a local place as close to equal as Frontera Grill or Topolobampo (Rick Bayless) in Chicago. Topolobampo is the more formal of the 2, Frontera more fun. Milagro's in downtown RWC on the corner of Middlefield and Main is one of the closest I've found. Went for lunch, recommended by a friend, and although service was a little slow due to the holiday lunch crowd, I was impressed. Great tequila and Margarita list, more extensive by far than most in the area. Had the duo of ceviches (mahi-mahi) and both were excellent, then the Enchilads del Mar (shrimp, scallops, mahi) and also very good. It seems that their slow cooked meats are a specialty, such as classic barbacoa, but I'll have to go back to try again. Have been to many others, including Maya (not impressed) and this may be the closest to Fontera in terms of menu, tequilas, overall atmosphere. I didn't see some of the surprises that Frontera has, duck tacos, various moles (though they had at least one), and service could be a little more refined, but recommended.
