True, does not mean these are actual issues though.
Also, if 2nd Ave deli was one of a multitude of outstanding jewish delis and it closed, we would mourn and say "at least we still have <insert multitude of deli names>". Instead when 2nd closed, a lot of people looked around and realized there was not much more to see.
The demise of a place like this makes you stop and realize that if something is not done, this cuisine can easily be lost. I would argue that for all intents and purposes, this cuisine has been lost for a very long time. at least to the public consumer. I still make kishka, kasha varnishkes, latkes, corned beef/pastrami, gefilte fish and liver knishes from my family recipes and I am sure others do too.
But the places I can go to get reputable versions of this are dwindling and that is a sad thing.
