PLAYESCAPE
Recently went to this - highly recommended - definitely one of the better escape rooms. It is, however, on the pricey side, and this code brings it down to be more comparable with other escape rooms.
This promo code was available in their foyer.
They are also on the Entertainment Book (25% off for up to 4 players) - while I suspect that it would stack, I cannot guarantee it.
Bookings Essential.
