It started as a pop-up shop during Winter Walk last year and stayed on, offering high-quality artisan chocolate in all forms at its outpost location on South Front Street. But now the Chocolate Bar is moving in with Verdigris Tea Shop at the corner of Warren and Second streets. On Saturday, September 15, there will be a celebration of "marriage" of the two shops. Guests are invited to sample a two-tone wedding cake paired with wines from Fairview Wines & Spirits and to taste custom-made chocolates from Christopher Norman. The celebration takes place from 5 to 7 p.m. at 135 Warren Street.
