I used to work across from this place, but I did not notice it until about 2 months ago. You wouldn't think it from the outside or even from where it's located, but this is one of the funnest and most unique experiences I have had in Boston. It's an interactive experience that seemingly transports you back to ancient Egypt. A Pharaoh gives you challenges and you have to navigate your way from room to room trying to get to the burial chamber. There are fun surprises and it's very entertaining. They also offer group rate if you have a lot of people. It's also a fun place to take a date.
