Are there crawfish in Thailand? Would Thai people like cajun food?

I wanna open a cajun restaurant in Thailand

Hi, I am Thai but lived abroad for a big part of my life so I think I have the views of both foreigners and Thais and hopefully I can help shed some light on this issue. For the first question, yes there are crawfish in Thailand, although they are much more expensive than regular seafood (shrimp, fish, squid, etc). Cajun food is still pretty new in Thailand, I know of a few in Bangkok (capital city) and they are pretty good although I must say 90% of the customers are expatriates who live in Bangkok. So It really hasn’t hit the main stream yet. Personally, I think it will be quite difficult to break into the ‘mass’ Thai market. In my humble opinion, your best bet would be to open it in a more touristy or areas where there are more expatriates, particularly white caucasians. I think your main destinations could be (list is not exhaustive): Bangkok, Koh Samui, Phuket. GOOD LUCK!
