Boston was the home of the first chocolate factory and the birthplace of Tollhouse cookies and hot fudge sundaes. This tour takes visitors with a sweet tooth to three culinary landmarks: the Top of the Hub for a featured chocolate dessert; the Omni House Hotel, where the first Boston créme pie was made; and the Langham Hotel, home of the famous Chocolate Bar in Café Fleuri (pictured). The tour also serves treats and chocolate trivia en route.

Tour begins: Trolley Stop Store at 2 Park Plaza, on the corner of Boylston Street and Charles Street South at 11 a.m. and 12:15 p.m.
