Office building owners in Manhattan are engaged in an arms race of amenities to attract and keep tenants who are demanding a "hospitality" vibe at workplaces in order to give workers an experiential treat every time they come in to the office.

"Amenities" have been redefined to include two-story-high, coliseum-style steps where hundreds of people can gather to watch two giant flat screens broadcasting global sporting events all day—on their way to work, or on their lunch breaks, of course.

According to a report this week in the New York Post, some landlords are reaching for the nuclear option in the tenant amenities war: tenants are being given access to the amenities in any building in the owner's global real estate portfolio.
