We visited Roundabout for my friend's 30 birthday. We've done a number of Escape rooms across the city and this one definitely was one of the better ones.
We played "The Prisoner" and while on the surface the room seemed like it was going to be pretty straightforward it was actually quite a lot of fun. My biggest complaint about escape rooms is they can sometimes feel like just a series of combination locks that you have to open one after another. The best ones use a variety of locks, a unique mixture of puzzles and production value and have a fun story to tie it all together. The Prisoner ticked all these boxes - it also featured one of my favourite gimmicks so far (which I won't speak much of to avoid spoilers).
If we had any complaints it would perhaps be with the staff who didn't seem overly attentive and were pretty complacent about our escape (most other escape rooms we've tried they at least cheer for you and let you know your time, here we had to tell them what our time was). This is pretty minor though, since the fun is in the escape, not what happens after.
The cost is reasonable for downtown, and as always is certainly a lot more fun with a group of friends than going to the movies or something.
We'll definitely be back!
