Atmosphere
So this is the place me and my friends would go after classes considering its proximity to Concordia University. We were not picky and we were attracted to the different promos going on Tuesdays and Thursdays. It has three floors, the basement which is considered a club (in all honesty, they shouldn't), the second floor is a nice bar with a live band (usually) and the third floor is Karinas (always empty but a good spot to rent for private events). Needless to say that the spot I usually go to is on the second floor: they don't have a cover on weekends and they have a much better terrace than the basement. The band I usually get when I go is pretty good and the feeling of the place is very casual. It has the same feeling as a McGibbons or an Irish Pub. Winston Churchil gets a 3 stars for the atmosphere.
Drinks & Food
I am not a big fan of the drinks served at Winston Churchill. Besides their Sangria, every drink that is not a beer was poorly done. The only positive point that Winston Churchill has over other bars is that it is cheaper. On Tuesdays they have a special which is $2.50 for the drink and $4 the beer, which in my opinion, is a great deal. The food aspect of this place is as you would expect bar food to be (typical nachos and fries) however what is interesting with this place is that the food is not the same from one floor to another (probably because the vibe of the floors are different: the basement being a ''club'' and the second floor being a bar with a pub feel to it). This Montreal bar gets a 2 stars for its drinks.
Service
The service on the terrace is usually really bad, with the exception of one or two good waitresses. I don't think I have ever got so much attitude coming from a waitress before. However, if you decide to stay inside on the basement level, I would go ask for a bartender called Valerie. She is very nice and talkative and will make sure you have a good night. The service of this Montreal bar gets 2 stars.
Location
The location of Winston Churchill is particularly good during the summer considering it is located on Crescent street (it's awesome during the Grand Prix weekend) and awesome for when you go to school downtown. Its proximity to metro Guy Concordia makes it really easy to access as well. For all these reasons, Winston Churchill gets 4 stars for its location.
The total amount of stars I would allocate to Winston Churchill in general would be 3.
