Wow, wonderfull!! I've been in Bangkok and further in Thailand, wonderfull country. You can of course eat a lot of fish. Also lots of dishes with meat and veggies. Beware of sauces thickend with cornstarch. They use a lot of fishsauce, this is no problem. Eat "steamboat"!! A hot tub with boiling water on the table and a large plate with raw fish, meat and veggies to boil yourself. Wonderfull!!
Bangkok I cannot help you, a little bit of the same kind of food I think.
Have a good time!
