Not all Chinese restaurants are the same. But you definitely should try China Keuken (China Cuisine). Not in the city entre, but you can always take a cab. This Chinese serves the best take-away food in town!
The food is excellent and the portions are very large. You get shrimp crackers for free (normally you pay 50 BEF, 1.24 EUR). And people who don't like Chinese food, can order chicken with French fries.
