You write it the same way as you do in English: Restaurant
The only difference is you say it a different way.
"In dem deutschen Restaurant"
at a restaurant = in einem Restaurant
Restaurant is the translation in German. It is translated from English to German. German is mostly spoken in the European countries.
das Restaurant
The German word for write is schreiben.
The restaurant known as the Seasonal Restaurant serves food that has a German influence, but with a modern day twist.
It means to write. Comes from the German word to write.
You should write French with a capital letter, so French restaurant is correct.
My is mein/meine in German.
Grüße
'you will be misssed' in German
Gastatte (with an umlaut over the second "a").
