I think this is one of the best hidden secrets in Frankfurt. There is a restaurant on the bottom floor of Karstadt shopping mall. Near the fish store, which is by the way, one of my favorite stores to buy fish in Frankfurt. You can buy your fish and/or meat, which the chef will cook for you with a salad, potatoes, or some grains. I love the concept because you get to choose your main ingredient and they have it cooked in a "surprise" way. You don't know what you are going to get in the plate, how he is going to prepare it. It is really fast, and you can have a great meal in short time. I feel I should not be sharing this one in yelp, because I don't want this place to get overcrowded. Don't expect fancy though. read more
