Kampai is beautiful as all the other reviewers have remarked. The interior is huge. It takes up the entire lower level of the part of the Fabourg it occupies and it's become the go to spot for basic Montreal biddies to get dolled up and take photos.
As a result, this place has become CROWDED. Unbearably so. Even though there's a line around the block most Friday and Saturday nights, there are always way too many people inside making the Kampai experience less than ideal in terms of service speed and comfort inside.
Kampai has a decent variety of interesting drinks named after some relevant pop culture figures. We had the Pikachu and were tempted by the cocktail named Starboy. The drinks were delicious but light on alcohol. At 60oz for $30 it wasn't overly pricey and reasonable to split between friends. Pitchers of beer will come in similarly at $25/60oz.
The food is okay. I wouldn't come here for a meal necessarily because it tends to be quite loud and appears to be much more of a drinks place.
The lower level has some games such as basketball and foosball.
Overall a good concept but maybe wait a few months for the crowds to die down before making the trek to Kampai.
