I recently visited Montreal for the first time and stayed right around the corner from this place. We got into town pretty late in the evening, and decided to stop in here for a quick dinner.
I had the Pad Thai with chicken. The portion was huge, especially considering the very reasonable price. The dish was decent--I've definitely had Pad Thai elsewhere that has been much more flavorful, but it wasn't bad.
Service was pretty quick, and you pay at the register once you are done so you can close out/pay at your own pace. Also, as an FYI, it's BYOB.
