After hearing about it many years ago I finally had a chance to taste samphire three weeks ago while in Istanbul.
I have never seen it here in the Bay Area, but in the past I have not made any special effort to find it, either.
After telling about it at work, my colleagues are asking me to find a place that serves it.
Any restaurants that serve it in the Bay Area?
Alternately, any markets that sell the raw plant?
