Extremely difficult to find!!! We went to two separate executive lounges before we were directed to the ' Mastercard' lounge. the food was average to below average, there were cookies and so on from Costco; and the sandwiches had a sameness to their style and quality that did not appeal. The cappuccino machine was broken and no alternative was offered. Frankly, the only good thing about the lounge was the limitless open bar. It was also fairly crowded, in comparison with the other lounges ( which we didn't have tickets for) All in all, I would rate this Montreal lounge as not worth the money
