The concept might not be named The Warehouse, but it's by the folks that bring you The Hastings Warehouse, and The Famous Warehouse in Vancouver.

The Hastings Warehouse has ALL their food for $4.95. Drink are of course more costly than $4.95. This place is always packed and you will always see groups of people drinking. Even though it is on Hastings, it’s not sketchy at all.
