This is the coolest place I've been to in Calgary.
You definitely need to make reservations in advance and can't expect to get in on a weekend without them.
Their drinks are so fabulous! The setup is just indescribable. This makes an excellent date place for a few drinks after dinner, or a great location for a group get together (max 6 comfortably).
Our servers were the sweetest and ensured we were well taken care of. There was no point where you needed to hunt someone down. They were sociable and well versed on drink options based on your description of what types of drinks you like.
Beware if you're getting an Uber, they'll think you're supposed to be picked up at the front of the building, so walk around to avoid missing them:)
