There is Ermitage garden not far from the Garden Ring Road, between Mayakovskaya and Tsvetnoy Bulval stations, on Karetny Ryad Street. This is a small garden where there are three museums: Ermitage, Novaya Opera and Sfera. The first two can be seen on this picture. I took the picture at the end of September 2007 on my way from the dentistry, which was on the Garden Ring Road, to the work :)
