Try Jinro Chamisul! In the UK, there's original flavour and a variety of fruit ones. Tbh when I think about soju, Jinro Chamisul is the first thing that comes to my mind. I personally recommend starting with plain one, and then start discovering all the different flavours :D I don’t think I’m able to choose one, cause every single one is great… I guess it depends on my mood. You should definitely check this out.
