This is great!! Petersen's is one of those great small businesses that are so much fun to find. The ice cream is delicious and the hot fudge is the best kind, thick and chocolatey. They also have the best pecans to sprinkle on a sundae, salty and sweet. It's a lovely little shop with a pressed tin ceiling from the original Petersen's in Oak Park, IL, marble topped tables and a very helpful, friendly staff. Terry is so enthusiastic about his product that it is infectious. I am thrilled to see this Chicago transplant.
