You've been debugging and it's 1 am and you've haven't even had breakfast. Here's where to get food late at night in Silicon Valley. My favorite is Fu Lam Mum on Castro in Mountain View. No-nonsense good Chinese food. There's always people there, even at 1am. Chinese restaurants are open on most holidays, including Bunny Day, Turkey Day, and Pine Tree Day.
Look for 24/7: They're open 24 hours a day, seven days a week.
Okay, Denny's isn't so great, but they're open 24/7 and it's eatable. Mostly. Tip: Avoid the mixed drinks. Bleagh!
If you know of other places (or if a place changes their hours!) drop me a note. To qualify, they should serve full dinner at least till 11pm. (This list was updated June 2006 by Kennita Watson. Many thanks!)
Denny's. 442 W. Calaveras Blvd., (408) 262-9090. Hours: 24/7
Milpitas Square. A bonanza for late night food is Milpitas Square, the Asian shopping center at 237 and Milpitas. The center store is 99 Ranch (the Chinese supermarket). Hop out from 237 onto McCarthy Ranch Road and go south. At the first stoplight, turn left, and after two blocks, you're in Asia: Chinese, Thai, Vietnamese, Singaporean; everything is there. They're open nearly every day and usually very late. (Note: on the North side of 237, there is McCarthy Ranch Shopping Center. This is the other shopping center.)
Jujubi. 550 Barber Lane (Milpitas Square), (408) 432-3395. Hours: till 1am Su-Th, till 3am F-Sa. Thai/Chinese/Fusion.
