Cosme, New York, now serves brunch from 11:30am - 2:30pm on Sundays.
I stopped by today for a late breakfast. The space transitioned nicely from dark and elegant at night to cool, breezy, and sunlit at noon. There aren't many places in New York serving chilaquiles, enfrijoladas, and sopa de tortilla at this level on Sundays.
Be sure to try Enrique Olvera's modern take on the tortilla soup, a cross between a lobster bisque and more traditional sopa de tortilla with a tomato-based broth.
