Ahh Ghiradelli. I used to frequent the location in San Francisco, CA during my tenure there and would get excited as a child who had just won a ticket into Willy Wonka's chocolate factory at the prospect of visiting the store. I have known about the existence of the Chicago location for a while, but never had the opportunity to visit it until recently. The experience was nostalgic for me, as it transported me back to the times I used to visit the San Francisco location with my wife and share an Ice Cream Sunday there.
The Chicago location seems to have a similar menu to the San Fran location, and the product quality is consistent with what you would get at the original location. The ambiance is lacking a bit, though that is probably because I am comparing it to my experiences in San Fran. The San Fran location is located on a slight hill overlooking the bay. The location cannot be compared to the Chicago location that overlooks a busy street. Regardless, Ghirardelli - Chicago is worth the visit, just come hungry. They offer a range of different sundaes and chilled drinks. There is also an opportunity to purchase some of the Company's products at the adjoining store which are worth a try for any lover of chocolate.
Overall, well worth the visit and calories. Don't be surprised if you find yourself coming here frequently after your first visit.
