The Lawrenceville Fire Co., Lawrenceville Water Co. (now part of Aqua America), Lawrenceville Fuel, and a U.S. Post Office are also located in Lawrenceville.
Lawrenceville was formerly home to a family grocery, hardware store, pharmacy, and, most famously, the Jigger Shop, which served generations of Lawrenceville School students as a school store and soda fountain [REF].
