I absolutely loved this place. Upon entering the Establishment you are greeted with a huge open space and even larger marble bar. The bar is dimly lite with "side" bars (instead of tables) where you can enjoy your drink. They play nouveau tech music which isn't as loud as most places so you can sit back, sip your wine, and enjoy a good conversation with friends.
We ordered a few bottles of an Australian wine. Sorry, can't remember the name of the wine, but is was scrumptious!
I noticed that most of the crowd was an after work crowd, so basically well dressed, casual business, smart casual. I didn't notice anyone with sneakers or jeans. I am sure that stylish jeans with some great sandals or shoes would fit in.
