A great place to go when you get back from SF. Pick Your City: Redwood City | Menlo Park | Palo Alto | Mountain View| Los Altos | Sunnyvale | Cupertino | Santa Clara | Milpitas | San Jose | Campbell | Los Gatos and Saratoga Late-Night Restaurants in Redwood City More Stuff: List of Breakfast in Silicon Valley and List of Happy Hour in Silicon Valley To qualify, they should serve full dinner at least till 11pm. If you know of other places (or if a place changes their hours!) drop me a note. Yes, Denny's isn't so great, but they're open 24 hours a day and it's eatable, mostly. I've worked at many companies ranging from San Mateo to San Jose.
The Chinese restaurants are also open on most holidays, including Bunny Day, Turkey Day, and Christmas Tree Day. There's always people there, even at 1am. My favorites are Man Bo Duck (now closed) and Fu Lam Mum, the two Chinese restaurants on Castro in Mountain View. Here's several places to get food late at night in Silicon Valley.
Well, you've been debugging and you look up and it's 11 pm and you've haven't even had breakfast.
