What type of food would you like? We need some more information. Where are looking to eat? No, I did not find any restaurants in the centre. I'm sorry but I don't have any belgian places in the centre. Can I try a different area? There are two Turkish restaurants in the centre of town. They are Efe's restaurant and Anatolia.
I want to eat at a moderately priced restaurant please Belgian please, i'm craving that lately I prefer to eat in the center of town, please. Hmm.. How about somewhere else in town, what is available? Why don't we try turkish food instead Either would be fine. Can you book for 1 at 20:00 on Tuesday?
