Locals in pattaya are friendly, I think it just depends, on the type of person you are. and how you treat them,
But just a heads up, A large proportion of the population of pattaya are not from pattaya, but i'm sure you know that on your trips there.
Also in pattaya you can find all the different styles of Thai food,
you just need to look. or ask a local Isan worker where the food you particularly like can be found.
it may well be, that the food of your choose is prepared by a member of staff from that very region.
Happy Pattaya and the sometimes, not so happy Falangs
