When I have friends in town, I take them here first. This is Mexico City Mexican food, done up by a formally trained chef and served in an airy, hip environment. It’s a lot different from the sloppy tostadas and refried beans of a normal Mexican restaurant. Start with the guacamole, tangy with lime, with warm tortilla chips, or the delicious elote callejero, a wood-grilled ear of corn with cheese and paprika sprinkled on it. Then start ordering tacos, which are about $3 each; two are enough, but you’ll wish you’d ordered three. There’s a selection, but try the carne asada and the al pastor (pork marinated with alluring achiote spice); there’s also shrimp, fish, and verduros de temporada (seasonal vegetables). Then hit the rest of the menu. For dessert, you have to get the deep-fried churros, which are basically donut sticks that come with three sweet thick dipping bowls: sweetened condensed milk, caramel, and chocolate. Yum.
