This is the location in First Canadian Place. It's open Saturdays, bringing a bit of life to the underground. They have a number of shirt and tie sales. Most of the ties are of the "dad's birthday" variety. Some of the shirts are quite nice. Despite the 50% off deal on many of the shirts, you're still looking at $150 for some of the sale shirts.
This store is two floors. It's fun to wander. Service is always friendly and attentive.
