I don't know about a Tatar quarter or Tatar restaurants, although a Yandex search brings a few up - e.g. see here http://zoon.ru/msk/restaurants/type/tatarskaya/

The upmarket Bakhetle supermarket chain (one on Tverskaya, one on Vozdvizhenka) is based in Tatarstan, and sells lots of chak-chak and probably some other Tatar food.

There is the Moscow Tatar Cultural Centre in Maly Tatarsky pereulok (lane), 8, metro Tretyakovskaya, tel. (495) 951-87-59 http://rtnka.ru ( in Russian only).

It seems like they also have the Idel tatar food restaurant there: http://www.afisha.ru/article/tatar-food-set/ I have never been there, just tried Tatar food while visiting my Tatar friends living in Moscow.

At the present we have no certain place in Moscow where Tatar inhabitans predominate. In the past, Middle Ages and up to the mid 17th century Tatars from the Golden Horde and Crimea settled in Zamoskvorechye, nice merchants' district on the left bank of the Moscow river, right in front of the Kremlin. Some streets and lanes there have preserved names originated from Tatars. Like Bolshaya Tatarskaya Street, Ordynka, Maly Tatarsky pereulok. All are to be found not far the Tretyakovskaya metro station.
