Despite what few have commented, this place is not hard to find. It is a delightful speakeasy, with real trees and a touch of daylight seeping in from the ceiling. I believe there are more/less busy hours, but I came on a Saturday around noon, and it was packed. Probably not the best study place at that hour, even with headphones. I had a peach hot tea, and a croissant (mostly eaten croissant pictured below). Tea was recommended by the cashier and was better than expected-very good, and although the croissant is not as flaky as meant to be, it had wonderful flavor and wasn't dull like some others I have eaten in Vegas.
Try this place out, it's super cute and very good so far!
