You're not drunk if you can lie on the floor without holding on
Great dive bar, somewhat cheap drinks, many pool tables and pin-ball games, all kinds of junk hanging on the wall - not "cute antique junk" - REAL JUNK! Free peanuts and resultant peanut shells all over the floor. Good selection on the jukebox. Many bar-fights have happened on a regular basis. Near Stanford university but outside the limits of their "no hard alcohol" rule that was in effect for many years, Antonio's is not just a student hang-out - many sorts of drinkers, drunkards, bikers, barflies and other classy low-lifes can be found there from the entire north end of Silicon Valley. Bad, but usually not totally gross bathrooms. There used to be a good "Hoffbrau" on one side of the room but now there is a Mexican resturaunt that serves OK food during the day.
if you do a web search on Antonio's Nuthouse you might find some pretty good comments...
