Ben and Jerrys factory is not in Manchester, but rather in Waterbury. The tour is interesting, and the thimble sized samples at the end tasty. There is a shorter option, and their ice cream is probably the best in the capital district region:

One of my favorites in Manchester is Zoe's. Try the meatloaf sandwich and the homemade potato chips!
