Crown Heights Salads

So first I was in a house and noticed abundance of special salads with the fish. I mean five or more 3-6" plates full of hot and spicy dips, etc. But then I noticed this in other two houses. I actually asked what is the source of this culinary innovation. Amongst the believable answers are the following:
1.Sephardic influence.
2.The influence of the Crown Heights caterer David Malka who sales thousands of meals every Shabbos and features assorted salads on his menu.

If I forget thee......: Food and the state of the nation.
