I was in Arizmendi a couple of days ago, and there was a sign saying you should reserve their hot cross buns for Easter.
I've never tasted a Hot Cross Bun...(other things in a bakery always seemed more interesting, and I have no childhood sensory memories of them...so..)
I also don't know exactly how they prepare them..as per the previous discussion of them a couple of weeks ago.
Arizmendi is located on 9th avenue between Irving and Judah (west side of the street midblock)in the Inner-Sunset
Tel 415 566-7113..
The Cheeseboard in Berkeley may carry them also.
