Ive been here every time ive visited Cologne. The burgers are incredible and the customer service is top notch. Id recommend the Rosemary Potatoes. They are are delicious alternative to chips. Now lets actually get down to business. The burger is fab. The bun is perfect. Toasted just right. The range of sauces are expertly made. The meat itself is a joy. Simple as. You will want this burger for Breakfast, Lunch and Dinner but struggle to get up as you will have a dopey satisfied smile on your face from a full belly. If you are in Cologne - Go here, or forever walk in shame.
