I dream of fresh grilled sardines on the beach in Portugal. Who has the
the best version, without the beach ok, in New York?
Casa Monon has wonderful sardines, though I can't remember off hand if they are grilled or pan fried - maybe check the menu on their website.
I spent a month in Portugal this summer- for me, the closest you can get is at the Greek restaurants in Astoria- Kyklades, Ploes etc. I have not found good simple grilled fish- especially sardines- in Manhattan.
Have you tried Avra at 48th & Lex (I thought they had a related restaurant on the UES, but I can't seem to locate it). It has fresh, grilled seafood and I'm sure they have sardines on the menu, if not as a special.
