Art deco gem the National Hotel was built in 1939 and, coincidentally, the clock above the bar is stopped at 7:39. For all you conspiracy theorists, 7:39 p.m. is 19:39 in 24-hour time. Legend says the clock stopped there so everyone could go back in time to the golden age of romance and glamour. We say the clock stopped there so it's always martini time. A gin martini arrives with tiny slivers of ice floating on the surface, like the wings of an angel. A shaker at your side provides you with a few more sips of this perfect elixir. Your body (along with your iPhone) tells you you're late for a date, but the clock — oh, that clock — says there's plenty of time for another round.
