Dining Outside the Home: China Poblano in Las Vegas, Nevada! For a mid afternoon break, rest your feet at the Cosmopolitan and people-watch awhile. China Poblano is a place where the menu features a magnificent blend of Mexican and Asian cuisine. Honestly, it works. One starring attraction is chef José Andrés’ created cocktail known as the “Salt Air Margarita”. Basically, the salty rim is eliminated and replaced with a thick layer of sea salt foam over fresh lime, agave, and tequila. It’s almost like taking a plunge into the ocean on a tropical island. Remarkable, refreshing, and invigorating. Well done.
