Canon Perdido has certainly lived up to its name as a street for lost restaurants-after all, even the long-running Jimmy’s Oriental Gardens succumbed. The great hold-out has been the Sojourner Cafe (134 E. Canon Perdido St., 965-7922), now open for 30 years. To celebrate the beginning of its fourth decade, Santa Barbara’s bastion of the healthful has redone its menu-but don’t worry, it hasn’t lost its tempeh. Instead, the Soj highlighted old faves, added some new twists, and is hoping to keep us all eating just the right amount. The new menu, you see, offers portion control-you can order that Conehead salad, or pretty much any dish, as a half or whole. Owner Donna Mudge explained, “We greatly appreciate the support of our local community and will continue to provide food that nourishes ‘the body and soul’ for years to come.” Don’t forget that, before stopping by, there are daily specials you can check out online (sojournercafe.com), and the sophistication and range of those might surprise you: The chipotle ranchero sauce on the pescado a la Veracruzana helps make the brown rice go down.
