Located in the Gaslamp Quarter at Fourth & Market (between Subway & Hooters).
I've done both rooms here, here's my 2¢Jason L.
Houdini's Hidden Workshop:
This room was well decorated and had some cool puzzles that involved finding clues then working them out from there. A cool plus in this room were the hidden passages and hidden compartments; it made it possible for players to search for new clues while others worked out what had already been found. This room had enough space for everyone to move around and concentrate on what they were doing. The majority of the puzzles were word related and/or riddles.
This room is much more intense with the addition of a frickin' zombie on a chain that chases you around the room. This room had more math than word puzzles and there were far less clues to find, so there was a good amount of people standing around while others worked on math problems. Granted, you could kill time by trying to lure the zombie away from the people solving but it made me feel sort like an idiot for spending 20 minutes playing tag with this chick in makeup and realizing that I paid to do it.
The room got hot real quick because of everyone running from the zombie and as the game wears on, the zombie's chain grows longer making there less space for players to work on their tasks which becomes tough to work around. At one point, I just went and stood by the A/C unit and let the other 10 people mess with some math problems because there was nowhere for me to stand.
Long story short: This place is fun but I'd skip The Lab and opt for Houdini's Hidden Workshop.
