The 40,000-square-foot facility will take over a portion of the old Big Bear in Mill Run.

Viktor Prozapas has embarked on a $3.5 million project that will feed people and help them burn off the excess calories.

Prozapas will open the Boulevard Grill and Get Air Adrenaline Trampoline Park in 40,000 square feet of space in the Market at Mill Run.

The concept will take over a portion of the long-vacant Big Bear at 3708 Fishinger Blvd., just outside of Hilliard. An early fall opening is planned.

The two-story restaurant, which has no relation to the former Boulevard Grill restaurants in Columbus, will take 5,000 square feet of space at the entrance of the site. With seating for 200, it will offer upscale and casual menu items, from steak and seafood to pizza and burgers.

A private dining room on the second floor will have seating for 45.

Entrees will be in the $10 to $24 range.

A trained chef will be in charge of the kitchen, so the food will be cooked fresh for both adults and youngsters, Prozapas said.

There will be many healthful options, such as 12 signature salads and fresh-fruit drinks. Children will be treated to a few favorites, such as hot dogs, burritos and french fries, given a special touch by the chef.

"We're going to take what they like and dress it up," he said. The dishes will be designed for speed so the youngsters can get to the trampoline-related activities, he said.

There will be no alcohol, something that was a personal as well as a professional decision for Prozapas, who said his liability insurance would have skyrocketed if he chose to offer liquor.

Instead, he said he will work on creating one of the best coffee bars in the city. It will have basic drinks and some more-sophisticated beverages.

Prozapas said the entire second floor and a portion of the first floor will have glass walls, allowing a full view of the trampoline park, and in particular a play area for children 7 years old and younger. The section will be cordoned off with nets and under constant supervision of an Adrenaline associate.

Because safety is a concern, there is only one exit and entry to the trampoline park monitored by a person at the front desk. In the same foyer, there is an entrance to the restaurant. Otherwise, patrons have to enter the restaurants through the doors facing the shopping center.

Prozapas said on his first visit to a trampoline park, be-fore he even took his first bounce, he wanted to own one. He said he loved the energy, excitement and youngsters getting exercise while having fun.

So Prozapas said he took his cue from personal experience, as father of William, 9, and Viktor, 8.

When he did his research on trampoline parks throughout the country, he talked to other guests who were waiting on their children to finish up their fun.

A common theme he heard: "I want somewhere to eat and relax."

"I see a lot of people doing nothing," he said. "They are bored to death."

Among the attractions at the park are a basketball dunk court, dodgeball court and a slackline, which involves balancing on a rope.

One of the chief highlights is the 90-foot-long "ninja" obstacle course with 11 different barriers, where two people can compete against each other.

The trampoline park will have five party rooms seating 25 each, where food from the kitchen can be ordered.

The plan calls for both the restaurant and trampoline park to be open during lunch and dinner hours daily.
