Klavon's is what I would imagine a soda/ice cream shop would be back in the 50's. There is a decent sized selection of ice cream flavors and concoctions but there isn't anything that's going to figuratively blow your mind. The interior is charming and has a lot of history -- just ask one of the staff and they'll happily tell you about its background as a drugstore.
It also offers a selection of old fashioned candy such as candy cigarettes, taffy, and marshmallow ice cream cones to mention a few. Klavon's is delightful and definitely isn't a bad place to spend a hot day in the summer.
