"Open late" marquees are attracting both revenue and rowdiness, local restaurant managers said.

Mandy Knox, assistant manager of Taco Bell, 322 W. College Ave., said the common late-night destruction has led the store to hire a security guard.

"We have our share of destruction, especially since we're open until 3 a.m. on Friday and Saturday," Knox said. "A month or so ago, somebody fell backward and knocked a huge hole in the wall."

Knox said tidiness is a problem for the late night crowd as well.

"It's really just a huge mess," she said. "Food everywhere and trash everywhere."

Knox said Taco Bell has recently been experiencing an influx of late-night customers because McDonald's has been closed for renovations. She said there is routinely a line out the door between midnight and 3 a.m. on weekends. She said the added foot-traffic has increased the amount of vandalism. To control the problem, Taco Bell hired a security guard to patrol the lobby Friday and Saturday nights. Tomorrow will begin the security guard's second weekend on duty.

"There's been a lot more rowdy people in here, so we got security," Knox said.

But not all late-night restaurants have found security precautions necessary for business.

Zach Myers, manager of Are U Hungry, 222 W. Beaver Ave., said his restaurant also experiences the negativity of late-night traffic, especially during football season.

"Anything big normally happens on football weekends," he said. "Especially when Eagles fans get in fights with Steelers fans."

Myers said the Are U Hungry staff has had to remove rowdy customers from the restaurant in the past.

"People get pretty obnoxious," he said, but added that hiring security was not worth the cost.

"We just say, 'If you want your food, then you'll calm down' and 98 percent of the time they calm down because they're drunk and starving," Myers said. He added that because of the small size of the restaurant, vandalism is not an issue, but theft is not uncommon.

Myers said customers have stolen both a stool and a menu board from the new Beaver Avenue location.

He added that Are U Hungry is open until 3 a.m. during the weekdays and 4 a.m. on the weekends because most of their business is during the late-night hours.

However, not all 'open late' signs attract destruction.

Amy Dawson, manager of Bella Sicilia Pizza & Pasta, 412 W. College Ave., said the restaurant is open until 3 a.m. on the weekends but does not encounter much vandalism.

"We have had just a few problems, but it's not very bad," Dawson said.

Dawson said the bathrooms are hit the hardest when customers use toilet paper improperly, but even those problems are rare.

"Overall they're pretty good," she said. "We have nice customers usually, we only have one out of 1,000 that'll be bad."

Dawson attributed this friendly customer behavior to the few employees that work there all day.

"There's only a few of us that work there," she said. "Most [customers] that see us during the day see us again at night and respect us more."
