Mission Street is a sure bet for two things: tequila and taquerias. If too much of the former leaves you craving the latter, check out Taqueria Can-Cun. The popular late-night menu of delectable burritos has earned the fanatical devotion of hungry bar-hounds over the years, but if you decide to sleep off the booze, try Can-Cun for breakfast. It might be a little off-putting to see the place in the daylight, but one visit and you'll be hooked. Like the night-owl fare, the daytime menu is quick, super-cheap, and consistently delicious. When you wake up with a vague memory of eating the worm, nothing can straighten you up faster than a couple of Tylenol and a big glass of Can-Cun's squeezed-to-order orange juice. If your stomach can handle it, try one of the traditional Mexican breakfasts -- rib-sticking favorites like huevos rancheros and huevos con chorizo. Though less-known, Can-Cun's morning offerings definitely rival its famous after-hours burritos.
