I'm looking for a great bar with an upscale speakeasy vibe in Boston (think Milk & Honey in NYC or The Varnish in LA). The kind of place that has a top-notch Old Fashioned. It doesn't have to be secret or hidden, but a dark, vintage style would be ideal. Also ideal: not impossible to go with a decent size group.
Alternately, a great whiskey bar would be great, but again would like to keep away from anything with a sports-bar vibe. Thanks!
