Nam kee
There are two Nam kee restaurants, but this one is the better one, actually rated as one of the best Chinese food restaurants in Europe. Do not walk away from the interior, because it seems a bit poor. Believe me when I write that the food and the pricing will make this more than up to you. The people serving are very nice and the service is quick. My recommendation is the very spicy chicken filets with noodles, but that''s just me. The pralines are said to be awesome as well. But to be honest,all dishes here make you want more the next day.
It is situated at opposite of the Nieuwmarkt (so not the one in the Zeedijk, around the corner).
In anyway, the Zeedijk is also called Little China town, and a lot of good cuisine can be found in and around this area.
