Yea..in my early years chionging FL, i remember seeing viets and indo too. Although Thais still remain dormant in that area. The funny part is many thais get sent back too. Probably its those OKts fault for over pricing viets, if not more chiongsters here can enjoy some viet locally too.
Probably the viets themself know their presence here so they also follow suit to steep prices. I dont personally feel 200 a pop its worth it. I can buy a plane ticket there and pop few times with the same amount. Oh well, Singapore is like this so we got to accept the fact

. Hope the market will change in the future though
