Try the $12.95 prix fix lunch at Angelina's II at 30 Berry Hill Road in Sysosset (516) 364-8234. They are also continuing the $24.95 Restaurant Week three course menu which is available all night Sunday thru Thursday.
Most diners have a $10 special that includes soup/salad, entree and dessert. I know people who eat there every night because it's cheaper than cooking at home, and the food is usually good and plentiful.
I like Pollo Rico in Centereach for lunch. They have a $10 special that has salad, chicken, rice, beans, plantanos and dessert. Delicious food, good price. The restaurant is large, clean and nicely decorated.
I'm not sure whether your post referred to mine, but I had a delicious serving of scallops over lobster risotto ($24) and my so had hanger steak ($20)The bread , too, was fresh crisp and delicious. We intend to return for Sun-Thurs special.
