Which place(s) get your vote for serving the best cocktails west of Kenmore Square? By "best cocktails" I mean something approaching the creativity plus craftsmanship of Eastern Standard, Prezza or No.9 Park, though I know that nothing suburban is likely to be quite that good. I've been resorting to places like the Met Club, Aquitaine Bis and the Capital Grille but their drinks just don't cut it.
The geographic area I'm thinking of includes Brookline, Allston, Brighton, Chestnut Hill, Newton and Waltham. No suggestions in Cambridge/Somerville, please: it's too long a drive and parking tends to be a hassle to boot.
