when i was in ny recently, i had a whitefish bagel sandwich from essa bagels and just about died. it was a thick cut of smoked whitefish and it was seriously the next best thing to fresh sashimi.
i went to the bagel shop on national/sepulveda on chowhound recommendations but was sorely disappointed with their whitefish salad bagel sandwich.
know where i can get a sandwich like i did at essa in new york? it doesn't even need to be a sandwich, i guess....just smoked whitefish (or really good whitefish salad) is fine.
