I've been to McCarold's several times and will definitely be back several times more. They have a great beer and scotch selection and the atmosphere is always friendly and chill.
Their kitchen also makes great pub food: make sure you try their onion rings! They have TVs, but they're on only when the Habs are playing, which is great (I typically dislike TVs at bars).
Only drawback is that you need to remember it is cash only.
