I'm currently on a donburi kick. I found a great place that makes katsu donburi out of chicken (not pork) called Bento Xpress in Milpitas (corner of N. Milpitas Blvd. and Calaveras Blvd., with another location on Jackson St. in San Jose). The katsu donburi consists of a bowl of sushi rice, topped with crispy chicken strips that have been mixed with shreds of bamboo. This is then covered with a dark, sweet and tangy sauce, and a slightly scrambled egg is poured over the top.
Would love to know of anyone else's donburi finds.
