It's worth skulking into the office late in order to snag one of the plump breakfast burritos that La Fuente, a groovy, low-rent Mexican joint, cooks up in a tiny kitchen that turns out big flavors. There are nearly a dozen manifestations of the breakfast burritos, all of which feature soft scrambled eggs and shards of crisp-edged potatoes, as well as your choice of bacon, chorizo, steak, sausage, beans or beef. But the crowning glory is the fiery, pork-punctuated green chile, either tucked into the tortilla or poured over it. Seething with intensity, these gut bombs weigh only slightly less than a newborn, and in the event you can't sink your teeth into one before the time clock calls you tardy, they're available all day, every day.
