Princeton Junction Station’s convenience mart is a godsend for famished and dehydrated commuters looking for a quick bite or gulp. It offers a garden variety of packaged and processed snacks, candies, and soft drinks. That said, the store’s relatively large interior is not laid out efficiently and could accommodate a greater variety of food items. Specifically, I really wish they sold more healthy food items, including fresh fruit and low-sugar beverages. Hoping to avoid empty calories, I’ve walked in and out without purchasing anything numerous times. Still, this place has its virtues, including hot coffee, granola bars, and operating hours that are invaluable to commuters(4:30am — 7:30pm).
