The Haven in JP is one of the best Scotch bars around. They have a ton of independent bottles and a lot of other rare and hard to find stuff like Octomores and Ardbeg special releases. If you’re a scotch enthusiast that’s the place to go (and they have Scottish food, which is excellent). Hops and Scotch in Brookline and Wink and Nod also have really big selections of Scotch, too.
