Only one word to describe 7 West's atmosphere and ambiance in the evening: sexy. The interior is relaxing and allows for you and a special someone to tuck away and enjoy some delicious house special drinks.
Personally, the service wasn't amazing. Sitting on the third floor took around ten minutes for us to get our first drinks, even though there's a bar on every level.
They don't take swipe cards either. My credit union hasn't mandatorily updated their cards to chip readers - leaving me to use cash. Luckily I had some cash on me, or I would have had to use their ATM with a surcharge. An inconvenience more than anything, as paper money is the most direct form of payment (IMO).
