The other good thing about leaving by the north metro exit at Mayakovskaya is that if you turn right and walk a couple of blocks you will find the Respublika bookshop and cafe. It is a place that many Muscovites like because of its contemporary feel. It sells art and design books, music vinyl and CDs and some designerly gifts. It also stocks a rather eccentric small collection of English fiction and - which sadly makes me very excited - is one of the few places in Moscow you can pick up magazines in English (and some other European languages).
The cafe on the first floor has been recently renovated and there are misc. art and design books in Russian and English to browse. And it has a mirrored ceiling.
