U: I need a cheap restaurant please.

S: Sure, I can help you with that. Do you prefer a specific area in town? Or maybe you'd like a certain kind of food?

U: Yes, portuguese food would be nice.

S: Nandos has restaurants in the south and the centre of town.  Would you like to book either of those?

U: Do they have nice indoor decorations?
S: I've read that the interior of Nandos is a bit dated. If you're looking for a more contemporary feel, I'd suggest looking at one of your other options.
