Seemed like the teenagers 'take over' around 6. We ALL liked it (and for different reasons). Decor throughout the museum was a well-organized display of junk, kitsch, vintage, the old, the new, and works of art and more. Plexiglass tubes run the ceiling for the furry creatures tiny 'piranha' fish are available for manicures and feeding time for the snakes and/or various other creatures could be a thrill if you're into that sort of thing. 'Aquarium' reminded me of something you'd see in the basement of an eccentric aquarium-lover type (but not in a bad way). Our meal ranked about a 7/10, wait staff was 9/10. It was fried goodness, but I don't need to do it again.
The attached restaurant was a sports-type bar if I remember, but was not busy or loud when we arrived for 'not to miss' fried ravioli'. Not 5-star dining, but great for breakfast fare. Not your typical donut and coffee buffet, rather real food and many options including a waffle making station. 'Happy hour' for guests with a 'real' drink ticket and nibblies AND breakfast was included. Nice hotel with lovely small pool and friendly staff. but not highly secured from what we could see.
Embassy Hotel (across from the FBI building) Parking was covered and ok.
