I eat Japanese/Thai/Vietnamese all the time and have rice. I occassionally eat sushi too, just not raw salmon, tuna etc... If it is from a restaurant and doesn't seem 'dodgy' it should be fine. My attitude is, if it doesn't look, smell or taste right, I don't eat it. That is with all food. I wouldn't eat reheated takeaway food though. I am 22 weeks pg and all has been fine so far during this pg.
