I've never been in Thailand.
I know what if I would travel there I would try local food but honestly speaking don't like an idea to add a fish sauce to every dish, because I prefer to eat chicken with a chicken taste but not with a fish taste and smell
I dont know where you ate thaifood, but there is a lot food without fish sauce ;)
I do believe there are a lot dish should be without fish sauce somewhere , because it's abnormal when ice-cream with that smell.
I tried few times Tai Cuisine here in Sacramento, CA. After ice-cream with fishy smell I stopped to try these again...
ice-cream with fish smell? I think you have been to the wrong restsaurants. I didnt like vietnamese food until I went to local vietnamese restaurants which were fantastic. it might be the same problem with thaifood in scarmento
