Watching some of the many youtube fresh market and street food videos in Thailand and Vietnam, I would really appreciate information on what the locals really pay for fresh seafood versus the tourist prices. Sometimes tourists in Thailand are paying 1800 Baht a kilo for admittedly nice prawns/shrimp, but that is crazy expensive ($80 a kilo). One restaurant video has giant freshwater prawns that cost about $70 for 700g. They look fabulous but that is crazy expensive.
Medium Freshwater Prawn 300g US$25 each actual, comments say US$4-8 would have been local price. Elsewhere a famous vlogger gets 10 very nice prawns for US$11.40 a kilo.
Giant Freshwater Prawn Restaurant price $70 for a 700g
Large Lobster/Rainbow Crayfish size 1kg+ 4300 PHP per kilo (more than $100)
I think it's reasonable for tourists to pay a premium of maybe 20% over locals, but maybe things are getting silly. Any local information would be appreciated and interesting to me. It's strange watching these videos and many times seafood prices are better in Australia.
