On Tuesday, October 31st, Bar Boulud is celebrating Halloween and the end of a long patio season with a dog-friendly Howloween event on their Boylston Street terrace. From 5:00-6:00pm, dress up your pup and swing by for special homemade dog biscuits from Pastry Chef Robert Differ. Biscuits are first-come, first-served, and there are only enough treats for four-legged friends in costumes, so break out those Super-dog capes and bumblebee wings and get ‘em while they’re hot. (Humans who arrive in costume will be appreciated, but will sadly not receive treats.)
