“We knew that college campuses were where we wanted to get into,” Piermarini said.

Insomnia Cookies was started by a University of Pennsylvania student in 2002 and has since expanded to 22 locations across cities and college campuses from its flagship store at Penn.

“I would say that they’re really great, the delivery is pretty reliable,” said Charles Bagley, a student at Penn. “I also think the cost per cookie is pretty low.”

Both companies have been looking to expand operations to Harvard Square for a long time.

“It’s one of those spaces we really wanted to get into, but it’s all about finding the right space for the store. It’s always been on our watch list,” said Sarnecky of Insomnia Cookies.

The increased presence of late-night businesses has brought excitement, rather than worry, to longtime Harvard Square business owners.

“It will certainly drive a lot of traffic and late-night business to the Square,” said Thomas J. Brush, co-owner of Felipe’s and Nochs. “I think there’s a lot of people out looking for different options. As more options for late night places open, it attracts people from more than just the immediate neighborhood.”

Brush sees promise in a new late-night scene of Harvard Square, citing the opening of a new concert venue on Church Street and its potential to bring more vibrancy to the Square’s nightlife.

Brush added that his business has considered delivery but has chosen not to engage yet.

“We thought about it, but we do deliveries only for catering, not on an individual meal basis. You have to make a commitment and dedicate staff to the service,” Brush said.

Delivery options for cookies have also excited students, who expressed an interest in having more late-night delivery options in the Square.

“I think it’s amazing. Having junk food in my insomniac hours would be amazing,” said Grayson C. Fuller ’15.

“Our rooms are going to smell really nice now,” said Paul Wei ’15, who lives in Quincy Swing Housing above the location on Mount Auburn Street.

“I’m so excited. They’re delicious,” said Meher Iqbal ’13, who has sampled the cookies at Insomnia Cookies’ New York City branch. “Because they deliver late at night, they’re popular among college students.”

When the cold winter months strike the Square, students will not have to leave their dorms to get fresh-baked treats.

“It makes student life a little easier a little more convenient,” said Robert C. Julien ’14.
