For historic Lewiston, Idaho, downtown has always been the heart of the city.  Most often referred to as “Beautiful Downtown Lewiston”, the area harbors museums, art and culture hubs, local boutiques, and of course, restaurants. One of those restaurants has been nestled quietly in the middle of it all since 2000 and has become a locally loved establishment. Main Street Grill started as a small burger joint under the name ‘Who’s on First?’ and has since grown into a full-service restaurant with an extensive menu, cozy atmosphere, and seating for 180, spread throughout the main room, a mezzanine level, and a beautiful outdoor patio. If you’re not sure what you’re in the mood for, we’ve got you covered. Main Street Grill has hand crafted burgers made with local beef, delicious pastas, seafood options, and more! A full breakfast menu is available from 8am-11am, with a limited breakfast menu available the rest of the day. 

Time comes with change, and like most businesses, Main Street Grill has undergone quite a few! The restaurant underwent a major remodel from January – May 2026. Updated menu items, new restaurant layout, and an atmosphere aimed to be a more Bistro-Grill environment are a few of the things that have changed. As the doors continue to open to both familiar faces and new visitors, Main Street Grill is ready to carry its story forward. Honoring where we’ve been, while helping shape what’s next for Downtown Lewiston.

Main Street Grill is a Happy Day Restaurant. Happy Day has been in the LC Valley since 1969 and currently operates 14 restaurants, a delivery service, a catering division, a local food initiative, and more! Come visit us, we can’t wait to serve you!
