My husband and I from the U.S.A. will be in Moscow at the the Marriott Grand Hotel in August. We have tours as part of our package during the day, but we are looking for things to do in the evenings/nights on Saturday, August 3, and Sunday, August 4. We are not looking for bar scene type nightlife, but we also do not want to waste time sitting in our hotel room. And obviously we want to be safe! Need suggestions!
