I will be in town this coming week staying at the Ritz Carlton/Four Seasons and am looking for a great place for cocktails somewhere in that general area. Willing to taxi within 15 minutes or so. Just looking for really well-crafted cocktails -- similar to the quality of Angel's Share or PDT or places like that in NYC. Would likely be going pre-dinner, but post-dinner is an option, too. Price is not a problem. Looking for a more upscale atmosphere rather than a chaotic scene. Any suggestions would be appreciated!
