AVONDALE — Sarah Knippel and her domestic partner Carlie Lusk planned to go to Hot Doug's Wednesday, then head to the court to be legally married in the state of Illinois.

But the wait turned out to be so long, the pair — both members of the Windy City Rollers — decided to go ahead and get married right then and there.

"After waiting for an hour, we decided why not just get married here," Knippel said.

After the decision was made, a friend used her phone to become legally ordained. Another rushed off to buy a wedding cake, balloons and champagne.

As word spread among social media, other friends came by to be a part of Knippel and Lusk's ceremony inside the restaurant.

"It was all impromptu, but it all came together," Knippel said.

In 13 years of business, owner Doug Sohn has seen proposals, engagements and has walked another bride down the Hot Doug's aisle.

But he said Wednesday was the first time a same-sex couple tied the knot at his famous eatery.

"When they came in with the balloons, cake and champagne, you just think, 'Well, how about that.' Something you haven't seen before," Sohn said.

After waiting for four hours, Knippel and Lusk, known as Moby Nipps and Baberaham Lincoln to their Windy City Rollers teammates, placed their orders and made their way to a table, where their friend officiated the ceremony.

Since Illinois legalized same-sex marriage earlier this year, the couple decided to wait until their anniversary so they would have to celebrate only one date in the future.

"It all came together, and it was very, very fun," Knippel said.
