If you're a big theater fan, you definitely need to go to a Broadway play. Visiting Broadway is a very touristic activity. Two-thirds of those sitting in the hall are usually tourists.
From the very first moments, you realize that this is not the right theater in the usual sense: they sell beer and sneakers during the intermission, no caviar or raffees. People in ball gowns walk next to people in ball gowns and sit in caps at the show. We're used to the crunch of popcorn at our neighbor's cinema, but now imagine the same thing at the theater. And actors who almost frighten with their pressure, but the audience responds happily in the same tone. On Broadway, you gradually pick up the wave and understand why this word has become a household word.
