Omescape is definitely one of the better escape game locations found in Markham. We tried the Joker's Asylum room and it was very challenging. The best part of this room is that your group is split into two rooms and you communicate to each other through and intercom.
The atmosphere of this place is very casual and you can play board games, video games or have a bubble tea before or after you do a room escape.
This place is a little pricier but you can save $5 if you check in on Facebook or Yelp. While convenient having a Presotea inside, I found the quality of drinks to be quite mediocre. I had a Milky Mango drink and it was way too sweet despite asking for less sugar. They made the drink twice for me and it was still too sweet.
Definitely go for the room escape. Go somewhere else for the bubble tea!
