We are from Long Island, NY and our friends are from the midlands in England.
We had dinner at Santorini. The food was OK, salty but OK. The bottled wine was PRICEY. Wine by the glass was reasonable.
My wife ordered a California Chardonnay ($6) and my friends ordered a Greek Chardonnay ($8). THEY WERE EXACTLY THE SAME. When I mentioned this to the waiter, he just smiled and said nothing. Both wines were good, portion was acceptable, but they rip you off on the Greek wine.
