I found this tour on tripadvisor and am so happy I did! We booked the one day walking tour with the premium lunch and were seriously impressed! Our guide Kate was the best! She was very knowledgeable and personable and we couldn't have asked for a better time. Unfortunately Red Square was closed that day but she worked around that little hiccup and ended at my favorite restaurant in Moscow! Pay up a little for the premium lunch and ask for Kate!
