Rice is actually one of the worst foods for bacteria, but as it's at a restaurant you should be fine...
I'd not have the sushi though, but chjicken teriyaki is fine & with hot rice will be fine.

My DH always cook rice & the refrigerates it to heat up as he takes it to lunch or adds to his main meals etc (like Hamburgers instead of a bun & salad he will have it with rice & salad!?)
I have eaten lots of his curries with rice that was cooker a day or so ago...
I have also been to numerous restaurants & had corries etc with rice!

I am craving curry big time at the moment!!!
