Among Shake Shack's most recent expansions this year were new locations in Manila, Singapore, and Mexico City. In Manila, you can pick up a calamansi limeade you won't be able to find anywhere else; in Singapore, look for a coconut-and-pandan-leaf beverage that was reportedly a hit with local tastemakers; and in Mexico City, you can order a concrete (the chain's term for dense frozen custard with mix-ins) with flavors of candied lemon, spice cookies, and local mamey fruit—a dessert developed by Elena Reygadas of the CDMX hotspot Rosetta.
