Troquet, Downtown Boston’s food and wine boutique, is about to get bigger and better. The team will start construction at 107 South Street – the former Bel Ari space – for a projected winter opening. Guests can expect an expanded menu of chef Scott Hebert’s French cuisine and a brand new bar menu at the renovated location. The reveal will include a private room, a large bar area and more seats in the dining room, where visitors can sit down to supper seven nights a week. In the meantime, reservations at the current spot can be made by calling 617.695.9463.
