Whether for the obligatory T-shirt and gifts or for drinks and/or a meal, the Hard Rock Cafe is a novelty place to view Rock Music memorabilia, while you eat/drink.
This location (close to downtown hotels) is less elaborate than other locations. There are no Cadillac cars hanging from the ceiling or coming out of the walls. But they do have lots of Rock memorabilia, including Keith Moon (The Who) and Bob Dylan shrines (and lots more).
The menu and food was consistent with other Hard Rock Cafes I have visited. I had a Beef Pot Roast with mashed potatos that was good. My wife had a large salad and French Onion soup (both good I'm told).
Hardly the Montreal experience, but if you want decent American food, the Hard Rock Cafe is a consistent choice.
