Buttercup Diner in Oakland

Jack London Square's family diner since 1988!

Open daily, 7:00 AM – 9:00 PM

Tucked on the corner of Broadway and 3rd Street, our Oakland diner has been serving Jack London Square for over three decades — long before the waterfront became the buzzing spot it is today. We're two blocks from the Oakland Amtrak station and an easy walk from the ferry terminal, which makes us a regular stop for commuters grabbing eggs before a train, weekend visitors in from San Francisco, and locals who just want a plate of pancakes without the wait. Sunday mornings, you'll find us packed with the Farmers' Market crowd heading down to the bay walk after breakfast. And if you're staying at one of the hotels nearby, we're the diner the front desk will point you to — scratch-made food, big portions, and the same recipes Debbie's been cooking since 1988.

Parking:
We have a small lot on-site (about 10 spaces) at the corner of 3rd & Broadway, plus metered street parking along 3rd Street and two public parking garages within a block — handy on busy weekend mornings or when there's an event at the square.

Breakfast Served All Day in Jack London Square

Breakfast runs from open to close, so the 2 p.m. pancake crowd is always welcome. The Extra Omelette is our most popular, and the corned beef hash and eggs is the one regulars swear by. You'll also find classic, Cajun, and Linguica benedicts, chicken and waffles, Banana Foster French Toast, and our house Frosted Cinnascuit, a cinnamon-sugar biscuit with cream cheese frosting.

Lunch, Dinner & Homestyle Classics

Later in the day it's diner comfort food made from scratch: Mom's Meatloaf, fried chicken, the All American Turkey Dinner, and prime rib, plus burgers like the Hickory Cheddar and the All American Patty Melt. 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. Try 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. Whole pies are available to take home.
