I really have to be on my best behavior when I enter the maws of a Korean restaurant. That means no Kim Jong Un jokes, no saying "Seouru Chak?-o" with an affected accent. No jokes about eating dogs, cats or other assorted household pets.
The fact is Seoul Chako has consistently provided very decent quality in the most convenient of locations at a decent price.
You could ask for more, I'm not sure you'll get it though.
Their sauces are tasty, their beef is tasty, that's the key. This is a Korean BBQ place. If you're ordering sushi here, you're doing it wrong.
The service is totally hit or miss. Either complete rubbish or awesome depending who you get. Seems to be the case for places run by Hong Kong expats.
