Ideas for restaurant for retirement party?

DH & I are thinking about throwing a surprise retirement party for his parents before they move to Florida. Since we are paying for it, and just had our wedding last month, we are looking for somewhere nice that won't break the bank.

Any recommendations? We are looking for Nassau or Western Suffolk.

Thanks!!
Cathy

Papa Joe's in Deer Park - prices very reasonable

Sal D's in Huntington - went to a Bridal shower there
