After the stress on weekdays and the debauchery on saturdays, good to remember that there are beautiful and simple things to see on sundays... like those roses in Shinjuku Gyoen
Sometimes I like to mingle with the plebe, eating simple street food , chatting with the common people... like at this seafood festival in Okubo park, with a very reasonably priced ikura/caviar don at 20,000 yens.
