With Spring Jam underway, Dinkytown businesses kept busy Friday and Saturday, taking advantage of the extra customers who were heading to the festival.

Toppers Pizza held its first Worldwide Topperstix Day on Friday — an event featuring 50 percent off any original order of Topperstix, as part of a franchise-wide promotion. And since it landed in the middle of Spring Jam, the Stadium Village store took advantage of the coincidence, said Pat Klasen, the store’s general manager.

Since Spring Jam is trademarked by the University, businesses aren’t allowed to use it in logos on advertisements. Instead, Toppers scheduled extra staff and sent out its employees to hang posters for the sale around Dinkytown.

“We were crazy from when we opened to when we closed,” Klasen said.

On an average Friday, Toppers sells about 40 triple orders of Topperstix. Last Friday, the store sold 219 orders.

Spring Jam events provided a way to draw crowds to Burrito Loco Bar and Grill and Blarney Pub and Grill.

For Burrito Loco, Spring Jam weekend is the busiest of the year, said owner Greg Pillsbury.

While they couldn’t print the Spring Jam logo, Blarney’s Facebook statuses declared the bar, “the place to be for Spring Jam Saturday night.”

Burrito Loco, meanwhile, didn’t find it necessary to do extra advertising. The restaurant had a banner that changed the wording to get around the direct use of “Spring Jam” but otherwise relied on the crowd milling around Dinkytown to keep busy.

“There’s so many people around anyway, I don’t know how much marketing you really need to do,” Pillsbury said.

Flaco Huevos, Mesa Pizza’s manager, echoed the sentiment, adding that an overflow of people is “a normal experience” at the restaurant.

“We’re pretty set up to deal with a lot of people,” he said.

The restaurant’s line went out of the door Friday afternoon, as did the line at Hideaway Head Shop a block away. But the store’s 40 percent off everything deal was part of its annual 4/20 sale and wasn’t planned as a part of Spring Jam weekend.
