Looking for fish place on LI
Specifically, a place that has more than just the usual (sole, tilapia, etc.).
I'm not looking for a high-end fish restaurant, but a "peasant food" sort of place, with things like grilled sardines and the like. A place where you eat rather than dine.
Location is relatively flexible, though I'm not looking to go into Queens. East End would be somewhat inconvenient, North Fork less so than South.
Ole Bar and Grill in Farmingville is Portugese and therefore heavy on the fish, and also the peasant fare in general (had rabbit stew last time I was there). I've had either sardines or anchovies (big ones) grilled, and they also make a great fish stew with unusual ingredients. It's on Horseblock Rd between Waverly/Nichols and 112, on the south side.
The Golden Dolphin Diner, in Huntington, has daily dinner offerings of grilled 2 lb whole tuna which, while not up to the Astoria versions, where they use a cage and both sides are equally grilled. Here, one side is grilled and the other appears to be pan fried. Good, but not great. They also regularly offer flour dusted and fried whiting and sardines which are also good but on the bland side. A call to the restaurant will confirm their daily availability.
