Salt Coke is a relatively new bar on Rodeo in Apgujeong. It's getting increasingly more popular because of the cheap drink prices in an area that is otherwise usually pretty pricey. I stopped in for a few drinks the other day. The bar itself has a trendy feel, it's minimal and mostly white. There's a dj playing on weekends. There's also a few projector screens playing movies, Toy Story was playing on the one by me. Awesome! The music was good and the bar was moderately busy. I think it will get much busier as more people hear about it though.
Cocktails start at 5,000 won and go up to9,000 for Mojitos. In this area you'd usually pay at least double that. They also offer various bottle sets. An Absolute Vodka set is 69,000 won including mixers and a choice of side dishes. So if you want a bar that still feels like Apgujeong without the price tag head here.
