This is a really creative concept for a bar and it's a great atmosphere. The door is mysterious and hidden, when we got inside we were informed the main area was full but we were seated in a private side area which was great for 3 people to hang out and chat. The bartender was really nice and helpful and she had great recommendations. Since there was no menu we gave our preferences and she got creative!
Our 3 drinks were each suited to our own tastes and completely different - mine was refreshing and tasted like cucumber and absinthe, my boyfriend's was citrus-y and light and his sister's drink was spicy and rich. Our second round of drinks was also well-suited to our tastes.
All in all the cost wasn't that high (around 10-15$ a drink) and it was well worth it due to the experience alone. Great music and lighting, and it was definitely perfect for a more intimate visit as well. Only thing to note is that it had a bit of an upscale feel and we were a tad underdressed in jeans and t-shirts.
