"Chef Colton Coburn-Wood of swanky South End spot Cósmica is hosting chef David Vargas of Portsmouth, New Hampshire’s Vida Cantina for a one-night-only pop-up on Tuesday, May 2, from 5 to 11 p.m. Vargas, who was named a James Beard semifinalist for outstanding chef this year, will be cooking baked haddock tacos, chicken drums with tamarind mole and a poblano relish, and a spring-y take on the Mexican corn salad esquites, which customers can order alongside Coburn-Wood’s spring menu for Cósmica." - Erika Adams
