S: Bangkok City serves Thai food, and is in the centre part of town. Would you like me to book it for you?

U: Can you tell me about the food portion size?
S: I found a couple of reviews that say that the portions are a bit small.  But I also found one review that said that they were large.  So I'm not entirely sure.
