Joanie's experience at Ruth's Chris made me realize how i have a very short list of where I can get a great martini. And, mind you, I actually don't raise the bar too high..., and as an ex-bartender I'm very forgiving:
a. a perfectly chilled glass, b. the glass is larger than a thimble, c. They know what 'extra dry' really means, and d. when I say olives, i don't mean a twist. Yes, very simple, but I continued to be shocked at how rare this is lately...esp. since the prices they charge now are steep.
Places that have nailed great martinis are at the franklin (w jody), harvard gardens (w/karen) and central kitchen (w kevin). I seem to recall having a great one at caffe umbra a while back (joe?).
(yes, it's become so far and few in between, experiences are standing out)
