I do food photography (mainly interior design and architecture) but do a lot of restaurants and enjoy shooting food when needed. Best part is eating it afterwards. I grew up in Plainview and the La Piazza there now used to be The Gallery, where I was with my friends every day after school. So it was cool when La Piazza wanted me to shoot food for them last year. Excellent pizza (better than the Merrick location) and great people.
Pizza supreme used to be in Roosevelt Field in the 80's. Still good, just out dated but who cares? Best Sicilain slices - Umberto's of NHP. Mostly go to the Wantagh location. The slices are just a bit small, need two. Haven't been here in years but - Eddie's Pizza in NHP, has incredible matzoh thin pizza with amazing sausage and pepperoni. I'm getting hungry typing this.
I'm a chinese food freak with shrimp. Three best places on Li for that is Hunan Taste in Greenvale, Northern Blvd., just west of Glen Cove Rd. Pearl East in Manhasset and still, the classic, Orchid in Garden City. Best shrimp and lobster sauce outside of NYC. All 3 have outstanding shrimp w honey walnuts, must try if that's your thing.
Lastly, there's a new ice cream place in Long Beach, Frozen Cow. Boldly opened a block away from the long standing Marvel. Crazy homemade flavors, coconut my fave. Also ricotta w figs (for the italians out there - bring some to your mom/grandma). They are so friendly and will let you try anything. Ok, need to fill my pie hole with some sicilian from Umberto's from last night. Better the next day!
