This is definitely my favorite restaurant in Dusseldorf, they have a lot of fresh ingredients, there are options in the ingredients for vegetarians, vegans, gluten free options so basically you can take your group of friends with you and everyone will be happy! I normally go there for dinner without reservation but if you are going during the weekends I recommend making a reservation to guarantee your spot! The sauces are amazing, they have explanation on what each sauce has and which type of meats or vegetables it matches, also information about level of spicy (I am very happy about this since I don’t like spicy food) they have 2 options, one you pay the weight of what you eat and the other one you eat as much as you like for a fixed price, if you eat less than 700-800g per meal I recommend the first option, otherwise go with the fixed price. The desserts are delicious as well, I love the chocolate one but they also have some Japanese and ice cream. I tried their lemonade and it is amazing, my favorite is the mango and passion fruit :)
