I've been here several times for low-key drinks and have thoroughly enjoyed my experience. The staff are thoughtful and informative. The cocktails are nuanced, but not in a pretentious way, and the atmosphere is spot on. After visiting the "speakeasy" at the Omni William Penn I have to say that Acacia is ten times better in terms of capturing the spirit of a Speak Easy and goes beyond being a bar with fancy cocktails, but provides an overall experience. I was even able to reserve the backroom for my birthday last year and the staff were very accommodating. I didn't give this 5 stars, because it would be great to have some nibbles available, nothing elaborate, maybe even mixed nuts or pretzels because some of these drinks are potent, in a good way.
