I enjoy the luncheon buffet at Christos. It is cloe to my workplace, making it easy access for business lunches. The food is consistent and I find it easy to get my fill (and alas more). the quality of the buffet food is good - not overcooked or dried out.
I enjoy the tomato soup, the salads, olives and tabouleh. I ususally get a bit of the gyro meat and rice with Stifado (beef stew) as well.
My vegetarian friend finds plenty to eat as well, either form the buffet or off the menu.
Did I mention the complementary baklava?
