521 Main Street Ribbon Cutting and Business Before Hours

You're invited to help us welcome one of Hyannis’ most beloved restaurants into a bold new chapter!

521 MAIN—formerly The Egg & I—has been a cherished part of the Hyannis community for over 50 years. Now under the care of a new generation, this family-owned restaurant continues its legacy with a fresh name and the same commitment to serving classic American breakfast favorites and comforting dishes made with care. Whether you’re a longtime regular or a first-time visitor, 521 on Main is focused on making every guest feel at home.

Join the Greater Hyannis Chamber of Commerce for a ribbon cutting celebration and Business Before Hours networking event as we toast to their next delicious chapter!

Come celebrate tradition, transformation, and community—all before your second cup of coffee.
