St. Louis, MO (December 30, 2022) – Pizza lovers have a new choice with the opening of a new Mellow Mushroom restaurant in Chesterfield. The latest addition to the Mellow Mushroom family is located at 15525 Olive Blvd, Chesterfield, MO 63017.

St. Louis is famous as the “Gateway to the West,” and the operators, Michael Vienhage and John Burke, want to make their restaurant — their second location in St. Louis — the local gateway to great food and drink. Each Mellow Mushroom is unique in its design and décor and the Chesterfield location reflects a modern take on a mid-century design style.

The cornerstone of the Mellow Mushroom menu is stone-baked pizza featuring a crust made from five simple ingredients, including water from Appalachian mountain springs. Other menu highlights are freshly made salads, munchies, burgers, handcrafted cocktails, and a wide selection of beers, many of them local.

Highlights of the Mellow Mushroom Chesterfield location design include:

  • A giant “LOVE” art installation at the entrance to the restaurant
  • The waiting area is anchored by an art installation featuring a colorful mushroom painting surrounded by butterflies fabricated from vinyl  records 
  • Oversized stylized mushroom columns fill the dining area

The store wouldn’t be complete without reference to the music from the area, specifically the blues. The restaurant features a unique table designed as an oversized vinyl record that honors St. Louis native and legendary musician Miles Davis.

While many Mellow Mellow locations around the country have separate event rooms, this is the first branded as “Club Mellow.” This private dining room seats 34 guests.

By the Numbers

  • Interior space: 6,279 square feet / 165 guests
  • Patio space: 441 square feet / 52 guests 
  • Club Mellow Private Dining Room: Seats 34
  • Beer taps: 24
  • Employees: 90

“We are excited by the decision of Michael Vienhage and John Burke to expand the Mellow Mushroom family and look forward to supporting their Chesterfield location,” said Mike Foster, Chief Operating Officer at Mellow Mushroom. 

“We enjoy being a part of this community and the restaurant emanates inspiration and warmth that is a great representation of the area and patrons,” said franchisee owners, Michael Vienhage and John Burke.

The restaurant at 15525 Olive Blvd, Chesterfield, MO 63017 is open Sunday through Thursday from 11 a.m. –  9 p.m. and Friday and Saturday, 11 a.m. – 10 p.m.

ATLANTA, November 2, 2022 – Mellow Mushroom has launched a newly designed menu at all 160+ restaurants that is a colorful combination of ultramodern and retro. The menu cover art was created by Florida artist Joshua Noom and pays homage to previous design elements used by Mellow Mushroom on t-shirts, advertising, and menu design.


The new menu art inspired the Mellow Wonderland holiday merchandise, which is available for sale at theyellowroom.com. Purchases of Mellow Wonderland merchandise help to benefit CORE (Children of Restaurant Employees), a non-profit that helps restaurant operations employees with children who face a health crisis or natural disaster. The menu and merchandise promotion begins on November 1, 2022 and runs through December 31, 2022.


Mellow Mushroom focused on a dynamic new menu with eye-catching typography to match the personality of the flavor profiles within the different sections of the menu. This “maximalism” style element – with extreme saturation of colors – enhances the menu’s combination vintage and futuristic feel. The design includes references to 1970’s ultra-graphic concert-looking posters which share Mellow Mushroom’s passion for creativity, quality ingredients, and hand tossed stone baked pies.


“The design and typography of our menus convey our passion for food, alluring design, and a bit of playfulness,” said Elizabeth Brasch, Senior Brand Director at Mellow Mushroom. “Joshua Noom captured the spirit of Mellow Mushroom with his cover design.”


Charity Partnership Supports Restaurant Industry


Mellow Mushroom is partnering with CORE (Children of Restaurant Employees) between November 1, 2022 and December 31, 2022. The brand is donating a portion of all sales from the new menu-inspired Mellow Wonderland merchandise collection for a minimum donation of $10,000. CORE engages a national network of corporate partners, sponsors, and donors to provide financial support and lend their voice to aid food and beverage employees with children who face health, natural disaster, or other crises. Documentation is required and an employee that may qualify can apply at www.coregives.org.


“During my time serving the food and beverage industry, I have met many restaurant employees with children that face adversity when a medical crisis hits or they lose their home or place of work due to a natural disaster,” said Sheila Bennett, CORE’s Executive Director. “We are grateful to partner with Mellow Mushroom to raise funds to help these families when life doesn’t go as planned and they face one of these crises.”


“The Mellow Mushroom menu-inspired merchandise collection timing aligned with the holidays and brings some fun and whimsy to theyellowroom.com. We are glad to be able to partner with CORE,” said Anne Mejia, VP Brand Development, Mellow Mushroom. “At Mellow Mushroom, we are passionate about the restaurant industry and its employees and CORE serves as a resource for our operators.”


With a bright palette of colors, the new Mellow Mushroom menu design is the inspiration for the Mellow Wonderland collection of apparel and poster prints at the brand’s online merchandise site, https://theyellowroom.com/collections/mellow-wonderland


Included in the Mellow Wonderland collection are:



  • “Mellow Dreams” 
  • “Magically Mellow”

ATLANTA, November 18, 2022 Mellow Mushroom has created a special cocktail for the holidays, a unique version of the classic Old Fashioned. Mellow Mushroom’s “St. Nick’s Old Fashioned” is a delicious take on the classic beverage, featuring premium ingredients with balanced flavors. It is available at Mellow Mushroom from October 25, 2022 until January 9, 2023.

The St. Nick’s Old Fashioned recipe features High West Double Rye Whiskey, Skrewball Peanut Butter Whiskey (contains nuts), Kahlua Coffee Liqueur, simple syrup, and Angostura Bitters with a lemon twist garnish.

“We want to establish Mellow Mushroom as a place to celebrate with a cocktail during the holiday season and lean into Mellow’s ability to blend flavors to make delicious craveable cocktails,” says Nick Arenas, Director of Beverage at Mellow Mushroom.

Key Ingredients – St. Nick’s Old Fashioned (Item is dine-in only):

  • High West Double Rye Whiskey – A unique and balanced flavor profile of cinnamon, gingersnaps, juniper, mint sprigs, and fresh wildflower honey.
  • Kahlúa Coffee Liqueur – Originated in Mexico in 1936 and features the deep, rich flavor of real black coffee, roasted chestnut, and indulgent sweet butter.
  • Skrewball Peanut Butter Whiskey* – A little salty, sweet, savory, and consistently smooth, with a natural peanut butter flavor. *Contains Nuts
  • Angostura Bitters – Adds a layer of complexity, intensifies the flavor of other ingredients, and decreases the harshness of spirits.
  • Flavor Profile – The rye whiskey creates the base with a bold spice character that, along with the angostura bitters, balances the simple syrup sweetness. The Kahlúa adds a hint of coffee and Skrewball adds a soft peanut butter finish.

The continued popularity of the Old Fashioned in the United States is due to the simplicity of the drink and how much the spirit shines through. According to a 2022 SGWS (Southern Glazer’s Wine & Spirits) report, the Old Fashioned is a top ten cocktail at both upscale casual dining and fine dining restaurants. Technomic Ignite Menu Insights, showcases a 5% growth in Old Fashioneds having a presence on menus and Peanut Butter flavored spirits with 65% growth in flavored whiskey cocktails.
