When it comes to urban charms,GoTravelDailyreaders just can’t get enough of Mexico. San Miguel de Allende, which topped our list for the past two years, may have been unseated this time around — it now comes in second — but it still draws gushing admiration. One reader called it “a unique art community in the mountains, with a mix of rich history and amazing food.” Another fan of the city praised its architectural diversity: “Gorgeous, sumptuous modern interiors are mixed with 500-year-old façades. You never know what delights you’ll find behind one of the beautifully carved doors.” Another town with a long and complex history and vibrantly colored buildings, Oaxaca (No. 5), gets raves for its sublime food scene, as well as its cooking schools. Mexico City leaped up our chart — last year’s No. 11 is now No. 4: “One of the most exciting cities in North America,” wrote one reader. “I go at least once per year, and every time I do it’s a new and exciting experience.” Another voter added, “The restaurants were excellent, from the corner taquerias to the upscale places.”
