We explored new places, and a newish Turkish place in Bellmore was quite good. They gave me sumac when I asked, and the kebabs were perfect. It felt (for LI) quite "authentic". The price was reasonable, and it was not crowded on Saturday night. Mediterranean, on Merrick Road next to Friendlys. The owner owned the Istanbul Kebab House in Lynbrook.
Onzon Thai, right next door, is also quite good (but tonight was crowded).
Final thought: Green Cactus (Mexican take out in Wantagh, Rockville Centre) is very good.
Thanks to those who made suggestions.
