The main attraction is the Original Goo Goo Cluster, a 1.75-ounce, 240-calorie handful of heaven that mixes milk chocolate, caramel, nougat, marshmallow and peanuts.
There is also the Supreme Cluster, which has pecans instead of peanuts, and the Peanut Butter Cluster.
Jesse Frederick, 20, who has worked in the store for 2 ½ years and is a walking, talking Goo Goo Cluster encyclopedia, said first-timers like myself should start with the Original and work their way up.
"If you never had a Goo Goo, get the Original. It will get you on board," said Frederick. "I recommend all three, but everyone needs to find their own favorite."
Frederick said the Goo Goo Clusters have been a Nashville staple since they were first made in 1912.
"It's part of our history," Frederick said.
