The outdoor entrance to this small cafe is like the entrance to a knock-knock club, hard to find and not inviting. Keep faith as you enter and proceed into the dimness, rounding a corner to emerge in a small, lamp-lit space with the cafe counter to your left. Now take two steps forward and look to the right. The view astonishes. Mammoth columns reach to the sky inside the Oakland Rotunda building. As if in counterpoint to the sublimity, the cafe serves simple, reasonably priced fare — toasted bagel with an egg option, pastries, and a standard selection of espresso drinks, four types of pre-made salads, daily soup, and sandwiches such as turkey and roast beef. Free wi-fi and a comfortable couch, with several issues of Oprah and House Beautiful neatly arrayed on the coffee table.
