How about the one at Chinatown ? How come different branches are different huh ?
Their Chinatown branch is very decent, I would say it's probably the best and most popular out of all their branches.
Difference lies in the ventilation and service, in my opinion. The Chinatown branch has decent ventilation, compared to the Novena branch where my shirt stank from that greasy BBQ smell, it's way less pronounced at the Chinatown branch, the air-conditioner is cooler as well.
Service at Novena and Tampines was quite bad, you have to ask multiple times to get them to change the foil, in Chinatown they automatically change it every 30 to 45 minutes, if I remember correctly. Didn't even have to ask once.
For the price, it's decent enough. Meat is marinated well. One of the better Korean BBQ joints out there in their price range.
