Yes, it is really called a Hidden Cellar because even though Roka Akor's underground bar has existed for about a year now, not a lot of people seem to know about this place. I've been here 3 times and only a third of the upscale bar was occupied each time even though the drinks are pretty good and the bar food, which I didn't get to try, looks reasonable. And I'm assuming that it comes from the same kitchen in the full service upstairs restaurant, the food should be of high quality. Thus the reason why this place is still under the radar perplexes me. For now, I'm happy to visit the cellar knowing that I can always get a good seat.
