I'm assuming something must have really changed in the past few years because I had a good meal!
Copoli is located right across Vendome Metro and conveniently close for many NDG/Westmount folk! The "ambiance" is kind of adorable. It's a no-frills diner with the griddle out in the open and tons of neon. Definitely brings on the nostalgia!
Their burger is HUGE. The image on the menu is actually to scale! Of course, its large diameter is mostly due to how flat the patty and buns are but you're still guaranteed to be filled up. The burgers were pretty good taste-wise, very classic. I got mine with a salad (lol) which was fresh and generous in quantity but the dressing was kind of tasteless. My date got his with fries which were perfectly thick and golden.
As for the service, we have no complaints. Our orders arrived quickly and our waitress was very nice and polite.
Overall we left satisfied. On a future night when we're feeling naughty and don't want to cook I can definitely see us coming back!
Fun fact: they also deliver!!
