Personally, I find looking into a lifelike replica of another human being a bit disconcerting, especially if it is a person I can identify with. Having seen many of the individuals represented in the museum in film and TV media, it is a bit bizarre to be standing there staring into their likeness. Despite the intricate level of details gone into making these wax figures, I still never felt like I was "hanging with the stars". The Wax Museum itself is laid out pretty well. There are several floors with a number of rooms that separate the wax figures in categories. The first room we entered was for movie and music stars. There were other rooms as well, such as sports figures and famous historical men and women.
There are two areas in the wax museum where you can sit and eat. One of them is about half way through the exhibit, and then another one near the exit. They both offer basic sandwiches, drinks, salads, and other deli selections.
If you don't already have tickets for the museum, I'll warn you that the lines are pretty long. We got there about an hour after it opened, and the ticket line was almost an hour long. Since this is a pretty major sight, I would recommend getting tickets before hand or online.
Although this is not the only wax museum in the world, it is probably the most famous. There are other Madame Tussaud museums around the world in other major cities such as Hong Kong, New York City, Amsterdam, and Las Vegas.
In any case, it is a good museum to check out and spend about 2 to 3 hours at, including a quick show in the Planetarium.
