I would be more than happy to assist you with that however, I need some more information please. There are quite a few moderately priced restaurants in the city centre. Do you have a cuisine preference? I do not have any moderately priced restaurants in the centre of town serving latin american food.
I would like to reserve a taxi from my hotel to the airport I'm sorry, I'll actually need a restaurant that's in centre and is in the moderate price range. I'd prefer something Latin-American, if there's something in the area. Nothing too expensive, but certainly not a fast-food restaurant. How about Italian food instead?

I am sorry there no Italian restaurants either. Would you like to try a different price range or food?
