It is very hard to believe it, but I am going to Russia next week. I have scheduled a jam-packed ten days of sightseeing in Moscow and St. Petersburg and have been doing a lot of research into can’t-miss restaurants. While some may not be enthused about the prospects of Russian dining, I have loved caviar on potato rounds with crème fraiche since I was three, and I can assure you I’m ready to return to this country with my maximum allotment of sea jewels. Over the past few weeks as I’ve perused restaurant menus at Russia’s most formal dining establishments, I’ve noticed an amusing theme among them: a sort of “France in 1958″ vibe that I simply can’t get enough of.
