Museum of Soviet Arcade Machines St. Petersburg
The Museum of Soviet Arcade Machines (Konyushennaya Square, 2B) is a real cabinet of curiosities, packed with some very curious cabinets indeed. It's full of lovingly restored old-school video games. Many bearing close resemblance to American classics.
It's easy to reach on public transport. Take the Blue Metro Line (Line 2) to the Nevsky Prospekt stop, or the Green Line (Line 3) to Gostiny Dvor.
