Hamza has two indoor locations in Nassau for sometime now Wigs.
The Hicksville one (where the truck gets all their supplies anyway) is in the back lot of the Apna Bazarr grocery store by the diner just off 106.
There is also one in Hempstead they opened right by the Hofstra bars shortly after Popeyes on your right headed west. However this locations portions aren’t as big but exploit the natives to the area and also have chicken wings and some other options Hicksville doesn’t.
From what I heard there is another Hamza in Commack inside a gas station but I’ve never been.
Once they opened the indoor Hicksville spot I never went to the truck again.
