Many eateries in Manhattan keep time with the Big Apple's nearly non-stop momentum, serving fast slices of fold-and-go pizza and giant, hand-held pretzels. But a step inside one of the city's Japanese kaiseki restaurants transports visitors to a very different New York. The pace slows to a methodical dance, highlighting as many as 15 fresh Japanese courses that shift seasonally, and are often plated with painstaking care. Short on time? Find the same tranquility at a tranquil teahouse in the East Village or a high-end wagash dessert shoppe in Midtown, both ideal spots to savor snacks and just a taste of zen-like serenity.
