Follow the flags to Build a Gut, the new sandwich shop and deli managed by Lorette Baccollo, Linda Baglieri and Tom Cavaleri on Beekman. Adorned with paintings of its bear-on-a-burger mascot, this small storefront offers a large selection of gut-busting made-to-order specialty sandwiches, homemade sausage, Daddy fries, char-broiled burgers, breakfast items, and fresh-brewed coffee.
