What else to do in Montreal?

We already have a dozen or more threads that I’ve mined for past visits, and I feel like I’ve hit most of the common suggestions people make. So I’m soliciting any hidden gems that might not make the typical lists for weekend visit. I will not have a car but will have ready metro access; I’ve gotten a lot of mileage out of surfacing at a random metro station and exploring a neighborhood. I like tasting food and drink.

Here’s what I remember visiting before (incomplete because I kept poor records/memory):

Museums:
Fine arts
Archeology and history
McCord Stewart

There are obviously plenty more: Museums | Montreal Museums
The biodome and science museums don’t seem my style.

I’ve eaten (and will continue to eat) so much:
Poutine
Smoked meat
Kouign amann
Bagels

Other places:
Mount Royal
Saint Joseph’s Oratory
Botanical gardens
Atwater market (I may visit again)

Cocktails:
Bar Bisou Bisou (lower-ABV sherry-based goodness; will visit again)
Coldroom (the speakeasy fad lives on in QC)
Cloakroom Bar (“we’ll make up a recipe based on what you say you like” with . . . mixed results)
Poincaré Chinatown (also, Kölsch in a proper Kölschglas)
Bar Le Mal Nécessaire (tiki)

I haven’t seen any shows. I suppose I could check out Cirque du Soleil on their home turf.

Old Montreal?

Notre Dame Basilica is supposed to breathtaking.

I enjoyed just wandering around window shopping in their extensive underground.

I really like the neighborhood of Lachine and the restaurant Il Fornetto there, but there are lots of nice dining options, many with outdoor seating.

May I recommend Sirene de la Mer, combination fish store and middle eastern restaurant. You can order from the menu or just choose a fish that they will prepare for you. The menu includes both seafood and other delicacies.

For a cheap pickup meal go to any branch of Basha, basically a falafel resto, although they have other things.
