A pair of Paramus residents are making an entry into the growing self-serve frozen yogurt market with Let's Yo, a new franchise from the founder of Retro Fitness.

While sister franchise Retro greets members with a blast of red, Let's Yo customers see green as they enter the store at the Gap Center on Route 17 south.

Green covers the walls, the signs and the iPads at each table. Marcello Petruzzella, who co-owns the Paramus Let's Yo with Russell Rothstein, said the look of the store, coupled with the sound and the experience, is meant to evoke excitement.

The entrance is adorned with velvet rope, and customers are directed to a row of yogurt machines. They can then garnish their yogurt with more than 30 toppings, weigh, and pay.

While there are a number of self-serve yogurt shops opening in Paramus, Let's Yo sets itself apart by inviting customers to stay and eat. The iPads, the free wi-fi and the lounge-style furniture are a draw to hang out.

Petruzella said Let's Yo mixes the vibes of an Apple store and a Starbucks. That was the pitch made when they first met Eric Casaburi, CEO and founder of Retro Fitness and Let's Yo.

"We thought it was a recipe for success," Petruzzella said.

Petruzella and Rothstein initially wanted to open a Retro Fitness franchise, but signed up for five Let's Yo locations instead.

"We felt it was more manageable," Petruzzella said. "We felt that we could express ourselves in the style and fashion of the place."

The Paramus location is the pair's first, but they have plans for Let's Yo stores in Franklin Lakes and Parsippany as well.

The Paramus residents believe they are filling a void in the community.

"We felt that there was really no great place to go where you could get a great tasting yogurt as well as that social experience," Rothstein said.

Petruzella has lived in Paramus five years; Rothstein for ten. Their business is already active in the community, sponsoring Little League baseball teams and looking into other ways to pitch in.

"We want to be the premier yogurt stop for not only Paramus but Bergen County," Rothstein said. "People have a lot of options and we think we're providing the best option for them to come and get great yogurt and a great social atmosphere."

The grand opening of Let's Yo is May 12.

"The entire world is invited," Petruzzella said.
