Food chain keeps eating up space.

In a continuing aggressive expansion program, Quiznos Subs, the nationally franchised specialty food chain, has leased six new Queens and Long Island locations, according to Sanford Zuckerbrot, chairman of Sholom & Zuckerbrot Realty LLC, its exclusive agent in these markets.

S&Z has helped Quiznos lease more than 45 new locations in the past two and one-half years.

With more than 2,300 outlets nationwide (typically 1,500 square feet in size), Quiznos has recently taken space at 61-19 Fresh Pond Road, Middle Village, and 163-15 Northern Boulevard, Flushing, both in Queens; 987 Atlantic Avenue, Baldwin, and 2731 Hempstead Turnpike, Levittown, both in Nassau County; and 536 Broadway, Amityville, and 225 West Main Street, Patchogue, both in Suffolk County.

S&Z's President, Franklin S. Zuckerbrot, and Managing Director, Doug Weinstein, report that Quiznos will execute leases for an additional five stores in the outer boroughs and Long Island by April in its sustained push for growth in key Northeast markets.

Adds Mr. Weinstein, "Quiznos' expansion plans call for opening a couple of hundred new locations during the next few years, and we are actively seeking well-located sites ranging in size from 1,200 to 2,000 square feet." S&Z works in conjunction with the exclusive area developer, ROC Corp. and Branded Concept Developments.

Quiznos, headquartered in Denver, has more than 2,300 franchised locations.
