In La Grange, The Elm restaurant is taking part, along with 35 other restaurants. The Elm is offering a two-course menu for lunch that will cost you $20, or a three-course dinner for $40.
"Everyone is excited, everyone wants to get out, do it responsibly, and just relax," said Dan Spain, owner of The Elm.
Restaurant Weeks are just one way that the industry is emerging from a long winter and even longer pandemic.
Spain is fired up and ready to welcome customers during the weekend.
"With our weather, it's 45 out and sunny, for some reason it feels like it's 60 - it feels great!" Spain said as the sun beat down Friday. "It's such a relief for not only us, for everyone."
The Elm was slated to open in March 2020, but it got caught up in the pandemic closures statewide. Like other places, Spain said the restaurant opened on a limited basis in June.
With Covid-19 mitigations improving across the state, they are preparing for restaurant week and the weeks ahead.

"To see the joy on people's faces, to be outside dining in a restaurant, and comfortable because it's so spaced out," he said.
All weekend, you can find deals at the 5th Annual Westmont Restaurant Week. McHenry County Restaurant Week is also underway, featuring dine-in and take-out deals.
And for the first time, Chicago Southland launched a week. The Flossmoor Station Restaurant and Brewery is one of 24 restaurants taking part Friday and Saturday.
"We want people to get out there and enjoy those restaurants," said Jim Garrett, President and CEO of Chicago Southland Convention & Visitors Bureau. "We're telling people 'Yes, we're open, and all we need is you.'"
