China Poblano in the Cosmopolitan is all about freewheeling culinary hookups, Mexican and Chinese cuisine getting together and being down for whatever. (Also, that thing about east-west trade going back to the 16th century.) The schtick extends to its cocktail menu, too, but you’ll sample some serious mixologist technique behind the motif with its China Poblano Cocktail Experience ($32), a generous four-drink flight of mash-ups. The Salt Air Margarita’s calling card is its soft bang and playful citrus/salt foam; the rye-based Ma is spiked with a bright tang of fresh yuzu and star anise ginger syrup for some bass. The Jade Garden blooms subtly with spice (Szechuan peppercorns), fruit (makrut lime) and herb (cilantro-infused tequila). My favorite, though is the Mezcal Negroni. Served in a small snifter, it’s a compact bowl of rich liquid smoke and golden fruit.
