Pancakes, eggs, bacon: they're all here, along with Americanized Chinese fare like chicken chow mein and dumplings. Also of note: they have a rare 100 health score from the DOH, which is definitely a badge of honor for a greasy spoon.

Reverse your breakfast with Art's hash-brown sandwiches, stuffed with mushrooms, onions and peppers and served with a side of eggs. Or opt for one of their Korean specialties, like the beef bi bim bop (also available in an omelet). Like many of SF's diners, it's owned by a Korean family, and they're known for their genial customer service.

Located at the very central point of Geary and Masonic, this no-nonsense, 24-hour spot draws night owls and drinkers for hash browns, pancakes, and potato skins loaded with bacon and cheese. Warning: don't pull out your cell to make a call, as it's against the rules.

This Korean-run NOPA diner has a Southern twist, with grits, biscuits, and collard greens subbing in for hash browns and toast (though you can get those, too). An extra dose of charm comes from the eclectic thrift-store coffee mugs; you're unlikely to get the same one twice. One note: it opens late for a greasy spoon, at 8 am on weekdays and 9 on weekends.

One of SF's only Portuguese restaurants, the Grubstake sneaks in hearty helpings of eggs with linguica, garlic shrimp, and caldo verde soup with the standard pancakes, burgers, and corned-beef hash. Prices are a bit higher than the standard greasy spoon, but the quality is higher as well, and they're open until 4 am.

The location in the thick of the Tenderloin may be a deterrent to some, but quirky offerings like turkey mac and cheese and the cheapest prime rib in town ($12!) draw an equal mixture of FiDi suits and downtrodden locals. It's open straight through from 7 am to 10 pm, so while it's not exactly late night, it's a good standby option.

Another iconic San Francisco facade, It's Tops and their "AWESOME HOT CAKΣS" are known to anyone who's driven down Market. Said hot cakes are awesome, as are the bacon waffles and apple pie. They're open until 3 am every day but Sunday, and they've got free wifi.

Another all-day, all-night refuge for the drunk and sleepless, Sparky's does a solid trade in milkshakes (try the peanut butter and banana Elvis shake), tuna melts, chili-cheese fries, and other favorites. If Chucky freaked you out as a kid, keep a wide berth from their creepy, redheaded namesake mannequin. They also deliver all night long.

Given its Mission location, it's no surprise that there's a Latino influence at Jim's, primarily conveyed through the housemade green salsa that regulars use to smother their eggs and hash browns. The chicken fried steak is popular, too.

While Jim's has a hint of Mexican about it, Red Cafe is more straight-up Mexican, with chilaquiles, fried plantains, and huevos rancheros among the highlights. The oatmeal pancakes are a slightly healthier alternative to the regular kind, and the standard bacon and eggs can be found as well.

Donuts are certainly available at this 24-hour Bayview spot, but those in the know come for drinks, 25-cent pool, and a blast from the past via the heavily '80s jukebox. Enjoy a shot of ouzo and a bottle of Bud with the Greek owners when the bar opens at 6 am, then head to the donut room for eggs, chocolate-glazeds, and pinball.
