Translation of chainring in German

The place was really modern and the food was excellent. We later found out that the restaurant belonged to a chain with the same name and was present all over the country and pretty popular.
thanks for the compliment! Can you understand me when I write in English? Spanish sounds so beautiful when spoken. I would really like to be able to speak Spanish fluently, since I am planning a trip to Peru.
I think I have to switch back to English. It will take me two years until I write an entire letter in German and I suppose I do not have the time for it. Does that mean that I am not serious about learning?
