Oh, Teddy, purveyor, advocate, and champion of all things honest, wholesome, and humane, from universal health care to national health insurance. We could all use a little more T.R. in our lives. Thus, the crowds will flock to Mad 46.

Like its Manhattan rooftop patio brethren, it has the usual pricey drinks and snacks and scattered umbrellas, but Mad is different. The fledging bar boasts three important draws: the killer location, the laid-back décor, and the hotel on which it sits.

Situated atop the Roosevelt Hotel, Mad's proximity to countless office buildings will lure the be-tied hordes for the all-important post-work rounds.

A strange Manhattan phenomenon, the white collar crowds love a good after-hours libation sipped in style at a hotel, whether they have a room key or not. Look for a mélange of the local and urbane, the traveling Blackberry addict, and the occasional bridge and tunnel expatriate.

Manhattanites love drinking on high; it stems from their superiority complex and a reverence for glittering cityscapes. Elevated outdoor watering holes abound, ranging from the fire-escape rickety to the posh and lavish.
