Within the convivial vibes of the Coolidge Corner Arcade’s second floor, at Cobble, chef and owner, Emily Vena, is reimagining the dinner party. Four tables, one seating, 12 guests, BYOB: It’s as intimate as a private party gets. The five-course, prix fixe Italian menu takes its cue from the seasonal vegetable haul. Currently on offer is English Pea Ranch Dip, Vegetable Crunch Salad, Fettuccine Vidalia ‘Fredo, Chicken Al Limon, and a Strawberry Short Stack for dessert. Here’s even better news: partner Rachel Trudel Vena has opened a BYOB bar downstairs called Bartlette (you bring the booze, they provide the mixers and accouterments).
