Lo Sfizio is one of the best spots in Cologne for Italian. With a deli in the back and restaurant tables in the front, it has everything you need. The food is absolutely out of this world and the service is great. Not only is their deli stocked with delicious Italian specialties, but they also sell cooking ingredients and equipment. Think of it as an Italian market/restaurant. Also a great spot if you're looking to relax and have some great Italian vino!
