al. Jerozolimskie 65/79 (Marriott Hotel), Warszawa 

On the 40th floor of the Marriott, this place offers sweeping views of urban Warsaw, glitzy Dynasty-style furnishings and a perfect platform to talk about mergers and climb the corporate ladder. Happy hour (19:00 – 20:00, two beers for the price of one) makes it possible to act like a big shot without having to sell the family silver.
