My girlfriend and I have gone to a bunch of these in LA. They range from little strip mall places with a bunch of janky puzzles with poorly translated instructions to fully decorated and themed rooms with actors moving the action along. Check reviews on Yelp first.
If you want to jump in, one of my favorites is "Trapped in a room with a zombie". They were featured on Big Bang Theory (don't hold this against them, and the room is nothing like portrayed in the show) and it's really well done--our zombie was hilarious. They have rooms in Boston, Chicago, Columbus, Dallas, Denver, LA, NY, Philly, and Seattle: http://roomescapeadventures.com/
In LA specifically, the Race/LA rooms are great: http://escaperoomla.com/ (Race/LA also puts on scavenger hunts which are also worth a shot.)
(Not associated in any way with these rooms, just a huge fan of the concept.)
