Times Square Parklet

Below 48th Street the seating in the Times Square Parklet was used by many people who sat and ate, drank, talked, read, looked at maps, talked on phones, and looked. Everyone seemed very relaxed. I felt relaxed. I do not associated Times Square with relaxation. Perhaps it's that Sunday afternoon in February effect again.

 It all looks so clean. I wonder how? See more text below.

Food was available in the center of the street (parklet)  at this location, but who cleans up the trash on the tables and everywhere else?
Who cleans the parklets? Is it the city? Is it the Parks Dept?

See the 34th Street Parklet post for a clue.
