The main thing Pullman has going for it, is an incredible chandelier, enormous yet made entirely of wine glasses. You can't miss it, hanging from the ceiling in the middle of the space. And when you look some more and discover it is made of wine glasses, it makes it even more striking (I will not post any links to photos of this art piece, you need to see it with your own eyes).
Pullman is a wine bar, that means that you'll discover tons of good wines there. And obviously, with good wine there is good food, like cheese, oysters, cold cuts and much more goodness.
A part from the impressive chandelier, the place is very well designed. Spanning 3 different levels, with slightly different feels, you'll be able to enjoy the new (bare concrete blocks on the top floor) and the old (bare rocks of the exposed foundation on the bottom floor).
Pullman is a great place to invite for both professional reasons or for dates. The classiness of the place will be much appreciated by your invitee, and the good wine cannot harm, in signing a contract or making your date more flirtatious.
