Montreal food tour

Hi everyone! In May I will be spending a weekend in Montreal and I'd love to go on a self-guided food tour along the lines of this one from the New York City board:

What I'm looking for is for you guys to help me plan a walk of a couple miles through some nice parts of Montreal with, of course, delicious food along the way! I'm not looking for sit-down meals, but rather places that are easy to stop by and grab something small. I'd like to try a good variety.

I'm from NYC and this will be my second time in Montreal. My first trip was last year and I went to: L'Express, Fous Desserts, St.-Viateur Bagels, Juliette et Chocolat, some other bagel places, La Banquise for poutine, Olive & Gourmando for muffins, Muvbox for a lobster roll, Jean-Talon market for produce, et Le Marche de Saveurs for a lot of maple stuff. I loved everything except Muvbox. I don't dislike any foods in particular and I do speak French if that makes a difference. I don't have any budget in mind but I imagine most food tour stops would be of the cheap eats variety.

Rotisserie Romados, Patati Patata, Schwartz's, Oliver Potier, Le Grand Comptoir, La Goulette all sound appealing, but they're kind of scattered all over the place.

I would like my route to include:
- A croissant place (the ones I had at Fous Desserts were good, but I wasn't blown away.)
- Some macarons or ideally a kouign-amann (these are hard to come by in New York)
- A pub or somewhere to stop for a lunchtime beer
- Something savory- my list already has too many pastries on it.
- What other small bites should I add? Things unique to Montreal? Things I won't find in New York? (I've read some other threads on this but I'm not sure which places might be good for a food tour as opposed to sit-down meals.)

Thanks in advance for your help! :)
