I've been to this place a few times and I would definitely recommend coming on a week day as you get better service and can sit at one of the many comfy lounge areas. My main reason for coming here was to enjoy their yummy mojitos and some good company. They no longer serve the mojito here, which is a shame.
On Fridays this place gets crowded with the local afterwork crowd and there is no place to sit and the bar is just too jammed, they also have bouncers at the front checking ID's, so the casual lounge vibe is lost.
Dress Code: Afterwork, casual smart.
