"Ali," by all accounts, is a popular name in the Caribbean island nation of Trinidad and Tobago. Multiple roti shops in New York go by this name. I don't know if any are under common ownership; all of them seem to run as separate operations.
This particular Ali is a genial fellow who serves generous portions; my salt fish roti ($8.50), shown partially unwrapped, was near full to bursting. You might burst, too, if you try to polish it off at one sitting.
