I've done quite a few escape rooms in San Diego, and Exit Game is one of my favorites for sure. My friends and I did the Harry Potter Room and the Villain's layer, and both of them were amazing!
There is a lot of effort put into the theme and puzzles of both rooms. I especially enjoyed the Harry Potter room. We had done a Harry Potter room in the past at another escape room in San Diego, and this one was infinitely better. I can't really get into the details because I'm not supposed to spoil the room, but I would recommend this room if it's your first time.
We had so much fun with the first room we did, that we all agreed to do a second room right on the spot (we had never done that in the past).
It's also free to do a room within a week of your birthday, so especially recommend coming here if you have a birthday coming up.
