Some of my friends are going out for lunch today and I don't know what I should do.

It will be at a sushi restaurant however I will order a meal (chicken teriyaki yum). I am just wondering about the rice which they obviously cook in big batches and leave in a rice cooker. Is this safe to eat?? My hubby doesn't think I should so I am thinking to give lunch a miss altogether but would really like to go out for a Friday lunch.

Any advice please.
