The Empress Lounge is lovely to behold, and the service is excellent.
The only complaint would be a slightly limited bar-food menu, and a smallish wine list. However, that wine list is almost 100% devoid of "the usual suspects," and that is a great big PLUS! Interesting wines, that one does not see everywhere. Now, it could be slightly expanded a bit, and as CityZen is using a Coravin unit, to serve B-T-G selections from more expensive bottles, maybe that will trickle down?
The service is excellent, and very friendly. That more than makes up for the small menus for food and wine.
