I thoroughly enjoyed my experience at Fox In A Box solving the zombie lab room and highly recommend it to all, at any experience level. My team and I (both veteran escape artists and a few novices) really appreciated the variety of puzzles provided. I don't want to give away anything but this room is VERY interactive and it involved far more than your usual brain teaser type puzzles. The owners are clearly passionate about FIAB as it shows in their attention to detail in the design of the room (again, I don't want to give away anything.) In short, just go to FIAB.
