To rent a car is about 2000 rials (not the best car in the world, of course).

Buffet brunch in a good hotel is around 200-300 rials.

Meal in a restaurant, depends of course what and how much you are eating, but say starting 100 rials up (per person. I'm talking an ok restaurant).

Visit at the doctor between 100 and 300 rials (general practitioner).
