This is a really nice, cozy lounge in tower one. There is plenty of seating in a relatively quiet atmosphere. If you are staying at the Signature, this is a nice place to chill out for a bit and have a drink or two. They have a good selection of drinks and they do have many specialty drinks on their menu if you want to experiment a little.
I was there a couple weeks ago and the wife wanted to take a quick nap while I wanted to have a couple quick drinks. So, I went there and had a couple nice gin based drinks. The service was perfect and the drinks came out quickly. Good show.
Will I be back? Of course I will.
