You can choose to invite your guests to a European restaurant, serving expensive Western dishes. However, many Chinese guests would much rather eat Chinese food! Especially if their visit has already taken them to other countries before arriving in your country, inviting them to a Chinese restaurant will often please your guests very much.
Your guests will also be happy to eat with chopsticks again instead of knife and fork. So save some money and have a bit of rice with the guests.
However, if in Denmark, many Chinese restaurants will disappoint, since the food suits Danish taste rather than Chinese. But a few restaurants we know about serve authentic Chinese dishes in Denmark :

Fu Hao reataurant, Colbjørnsensgade 15, Copenhagen (Denmark)
(Phone: + 45 33 31 89 85)

The restaurant is located in a bit of a dull neighbourhood behind the railroad station (next to Saga Hotel) – but don't be fooled! Here, you can even have dumpling, a treat rarely seen outside of China. But remember to ask for the special menu offering dumplings.
You will see a lot of Chinese dining there. This in itself is an indication of the quality of food served. Prices are also reasonable. All guests we have taken there on behalf of Danish companies have confirmed that this has been the most authentic meal served to them in Denmark.

Another two restaurants worth a visit:

Pak Ka, Halmtorvet 36, Copenhagen (Denmark)
(Phone: + 45 70 23 28 88)

Laihoo, St. Kongensgade, Copenhagen (Denmark)
(Phone: + 45 33 93 93 19)

In these restaurants you have to pre-order if you want something other than the standard menu such as steamed fish.
There are many good Chinese restaurants around. If you let your interpreter pre-order, it will often be possible to surprise your guests with local dishes from their home town area.

Inviting your guests to a Japanese restaurant is not a good idea, simply because of the problematic relations between Japan and China since the occupation during the 1930's.
