Master Redmond,
Looks like work is going to keep me from joining you in Montreal.
An area to visit is on St-Catherine's Street and Crescent Street area.
Some good restaurants/pubs/clubs.
(In this area: Hard Rock Cafe, Newtown (named after the famous Grand Prix racer Gille Villeneuve), and "Weinstein & Gavinos") I am not a fan of Hard Rock Cafe restaurants.
Montreal is known for smoked meat sandwhiches :
Very famous : Schwartz's Deli

(Not in St-Catherine's/Crescent area, but worth visiting)
Montreal is also known for steamed hotdogs and poutine (fries, cheese, gravy)
You can find these at any ma & pa restaurants on St-Catherine's.
Drink well, eat well, and have fun !
