Musee Mecanique: San Francisco's Weirdest Museum (VIDEO)

When was the last time you walked into a museum and were encouraged to touch everything?

Musee Mecanique, a hidden gem at San Francisco's tourist-filled Fisherman's Wharf, is as strange as it is interactive -- and it's one heck of a lot of fun. In a seaside hangar, you'll find an incredible collection of 19th and 20th-century penny arcade games -- all ready to be played.

When visitors are looking for something truly unique, Antonio Barrios, chief concierge of the St. Regis San Francisco, sends them here. Bring lots of quarters, he says, (though there's a cash-to-coin machine if you forget), and if you have any questions, look for the guy on roller-skates.

Watch the video to see what he means.
