Scratch-Made Breakfast, Lunch & Dinner in Vallejo

Our Vallejo diner sits right on Sonoma Boulevard, one of the city's main commercial corridors, making us an easy stop whether you're running errands nearby or driving in from Solano County. We're a short drive from Six Flags Discovery Kingdom, which makes us a go-to breakfast stop before a day of rides or a hearty dinner spot after one — plenty of families fuel up here before heading to the park and swing back through on the way home. We're also a regular for folks commuting off Sonoma Boulevard, and for anyone heading to or from the Vallejo Ferry Terminal into San Francisco who wants a real breakfast before the ride. Weekends bring a steady mix of families, longtime regulars, and Six Flags visitors — it's the same scratch-made recipes David and Debbie started with in 1988, just with a lot more parking than our original spot.

‍Parking: Free on-site lot with ample parking directly in front of the restaurant — no meters, no garages needed, which makes us an easy stop for large families or groups heading to or from Six Flags.

Get Directions

Breakfast Served All Day

Fuel up before Six Flags with a breakfast that runs from open to close. The Extra Omelette is our most popular, and the corned beef hash and eggs is a regular's pick. Kids and grown-ups alike go for the pancakes, Belgian waffles, chicken and waffles, and biscuits with sausage gravy, and the Frosted Cinnascuit, our cinnamon-sugar biscuit with cream cheese frosting, is a must for the table.

Lunch, Dinner & Homestyle Classics

After a day at the park, settle in for Mom's Meatloaf, fried chicken, the All American Turkey Dinner, or prime rib, or keep it simple with a burger and Humongous Nachos for the table. Our Jumbo Mozzarella Sticks are one of the dishes we're most famous for.

Pies Baked From Scratch

The P in ButtercuP is for pie. Save room for the signature upside-down apple-walnut pie with its brown sugar and walnut glaze, or the pumpkin pie voted best in the San Jose Mercury News and Oakland Tribune taste-off.
