The food is delicious and the staff is nice. The bread with the tzatziki was crispy, and it was a perfect match with the lamb skewers. The rice noodles were different than I'm used to, but in a good way because it was very good. The section of the restaurant in front of the bar with the 1/2 person tables is separated from the rest of the restaurant. The wooden chairs at these table were pretty wobbly so it didn't feel comfortable moving around a bit while sitting.

Noodles/rice was amazing, potatoes were well seasoned and we especially loved the bread and the sauce that came with the platter. Only thing was the pork skewers were relatively dry and hard to chew. Price was very affordable too for the portion! :)

The food was awesome, the service was like you are at home with your family. Lamb Koteletts and lamb meat on the stick that I haven't tried anywhere else was so good I couldn't stop eating it. For the starter we had deep fried zucchini with tzatziki and pastry with feta cheese and honey. Do I have to say that we were stunned and wanted more 😁. All in all if you are in Cologne you have to try the food and enjoy the atmosphere, and if you are lucky you will have an random musician playing live music for you. We will come again for sure.

Positively amazing food and atmosphere! We ordered the starter platter for two and the grill assortment platter for two.. and we couldn't finish the second! A LOT of food, everything absolutely delicious and welcoming staff too. To me, it felt the restaurant was one of those hidden secrets of Koln, where families get together for a Sunday meal and where the staff knows everyone. If in Koln, go eat there, you won't regret it!
