my humble opinion...high end spending working ppl (ang mo kids, law ppl, doctors, finance) will go zirca, zouk and spend. high spending 'ah beng' like us will go atlantis and neverland. we not used to high class place because we like to go in a relaxed manner, eg berms on a later night? if we rich ah beng starts to go moko, then i guess the rich spending working class may just siam us.
end of the day, ppl who frequent thai places must have a liking for thai culture. if they just want pretty gals plus some laba, they go prc joints and veit ktvs. i mean we dun go to thai pubs aiming to touch and f right? if can f, it's a bonus for the outing. esle we go back pcc and tell ourselves to go ktv better. but end of the wk, we get ourselves mao again back in thai pub.

maybe this new place can get the hi so crowd?
i believe that rich boys also go TDs. maybe they wanna feel casual tat day or dun feel like overt ktv action or chatting up girls at velvet.
