Its not your typical bar. As mentioned, you need a reservation just to walk into the place. And when you do have a reservation, it most likely will just be standing room at the bar. The host/hostess literally places you at a 6-8 inch gap at the bar - just enough for you to lean in and order your drink. As far as leaving with your drink, the drinks are served in glassware that are for purchase. If you decide to purchase it, they give you a clean unused one in a box when you're getting ready to leave. If you decide not to purchase it, you're just not charged for the glass. But either way, they'd have to transfer your drink to a different cup before you could leave since the glasses are for sale.
