I had dinner at the RYSE - Charr restaurant. Great menu, food and service. Highly recommend. The hotel itself is a bit of a bus station - but perhaps that’s part of the charm. However, I am not sure I would stay there.
The neighborhood is a really nice area. It gets very crowded in the evening, late evening with young people dressed to impress ! It’s a great contrast to the vibe of the rest of Seoul.
