When hunger strikes at 4 a.m., Princeton students do not have many options. Aside from the WaWa, area establishments offer little to no assistance in fulfilling students' middle-of-the-night cravings.
Hoagie Haven stays open until 1 a.m. on most nights, and Villa Pizza, at the Frist Campus Center, is open until 2 a.m. However, no restaurants seem willing to make the investment and remain open 24 hours.
The reason for this is one of basic economics, restaurant owners said. Staying open all night in the Princeton area would not be profitable.
Gus Liras — co-owner of Hoagie Haven with George Angeletopoulos said he would anticipate very few customers after 1 a.m.
"Even if 10 people came, I don't think it would pay to stay open," Liras said.
The experiences of local businessman Alfie Khan seem to confirm Liras' predictions.
Khan owns Abel Bagel. A few years ago, Khan tried keeping Abel Bagel open all night. He also opened adjoining restaurants Road Pizza and Princeton Peckers, which sold chicken, as 24-hour establishments. However, Khan said he had to cut back on the restaurants' hours because of a lack of consumer demand.
Khan also noted that it is difficult to find employees willing to work late-night shifts. Liras also said the idea of having people working around the clock is ridiculous.
Compounding the difficulties of operating a 24-hour eatery is that the student population does not live in Princeton for a substantial part of the year. A large portion of any market for late-night food would disappear every time the University has a vacation.
"We just don't have the big city environment here," Khan said.
The opening of the Frist Campus Center, which provided students with greater dining options, may have limited choices off campus, said Nina Langsam '03, the USG campus and community affairs chair. Two years ago, the USG discussed with PJ's Pancake House the prospect of staying open all night, she said.
PJ's owners considered the idea, but ultimately decided against it because Frist opened, Langsam said.

Princeton's hungry scholars are not alone. Harvard University students face a similar plight, said Julia Sheketoff, a Harvard student. The last Harvard Square restaurant to close does so at 2 a.m., and Harvard University Dining Services does not offer food options around the clock.
