As White House and university officials sort out the details of President Barack Obama’s visit to Ohio State on Sunday, many local businesses are gearing up for an exceptionally busy day.

“I can’t imagine what will happen,” said Alex Abejuela, assistant manager of Red Mango, a frozen yogurt shop on High Street. “I’ve never been in this type of situation.”

Abejuela, who was unaware of the event, said that a presidential visit to OSU is exciting, regardless of political beliefs.

Other business owners were more open about their thoughts on politics.

“We lean a little Democrat here,” said Jimmy Barouxis, owner of Buckeye Donuts. “If you see ’em, tell ’em to come here.”

Barouxis expects business to “blow up” at the 24-hour shop following the event. Other businesses, such as Conrads College Gifts, plan to extend hours.

“On Sundays, we are usually only open until 6 (p.m.), but we are going to play it by ear on Sunday,” said Bennett Cohen, manager of Conrads. “If we get busy, we are going to stay open.”

Businesses were already prepared for an unusual business day Sunday because of the Columbus Marathon, which runs from 7:30 a.m. to 3 p.m. and takes runners north on High Street along campus.

“We are excited for the president’s visit and the marathon,” he said. “If Obama stops into Conrads, we will give him a free T-shirt.”

Some streets will close during the rally and marathon, but some business owners aren’t worried that the closures will keep customers away.

“I don’t think the traffic aspects affect us as much,” said Liam Van Vorhis, general manager at Eddie George’s Grille 27. “Fifty percent of business is college kids that walk and ride bikes anyway.” Van Vorhis said he plans to increase the sports-themed restaurant’s staff by 20 percent Sunday night.

“Any time a major politician or a major sporting event is on campus, people come from all the suburbs,” Van Vorhis said.

Although football games draw the most business to Eddie George’s, Van Vorhis said he could not compare Obama’s visit to a Buckeye game.

The Blackwell, a hotel and restaurant run through the Fisher College of Business, is always fully staffed on weekends and will make no changes Sunday.

“We do have game-day traffic every weekend,” said John Clark, accounting manager at the Blackwell. “It’s pretty much business as usual.”

Businesses on OSU’s campus also plan to conduct business as usual.

“We are not changing any of our services at this time, so I have nothing to report,” said Karri Benishek, marketing manager for Campus Dining Services.

Kathy Grant, operations manager of Berry Cafe in the William Oxley Thompson Library, said she has not heard of any changes there.

“We rely on the library’s needs and, as of now, nothing has changed with our hours,” Grant said. “We think it will be busier. We welcome (Obama’s) visit.”
