This restaurant is exactly what Montreal needs more of. I'm a huge fan! Everything is delicious, homey and satisfying. My particular favourites are the perogies, pancakes, Cobb salad, and McArthur's sandwich. Great coffee.
Only drawback is this place is small, meaning it is usually packed on the weekends and guests are practically sitting on top of one another - so definitely expect a wait, and be in the mood to speak loudly & get cozy. However, if you live in the area, Foodora delivers from Arthur's, which is a great alternative in a pinch.
Tip: never, ever leave without ordering a babka. I'm not sure it's even on the menu - but you need it. Get both chocolate and cinnamon. You won't regret it.
