I went to eat this Korean BBQ with my colleagues on one fine evening. The shop is located at Toa Payoh Safra, not very far from Toa Payoh MRT station. It is something like buffet, but you have to order BBQ meat within 1 hour (plate by plate). After that one hour, you may still can sit down and chit chat at the shop but cannot order any food :)
In my opinion, some of the BBQ meats are not really tasty. The way they marinate the meat is not rich in flavor. I guess some of them are just raw meat and it is really not taste at all. Beside BBQ meats and some Korean salads, it also serves free flow Korean drink like Ice tea which is also taste wired because it only has aroma in it but don't have any taste/sugar like other soft drinks. May be they serve healthy foods which is not my type. :)
It costs about S$20 per person. For its standard, it is not really expensive but I would top up a few more bucks to eat at Seoul Garden.
