I found these cookies at a Brazilian grocery store in Little Italy in San Diego. I assumed they were named after the lead singer of U2.
These were a little disappointing. As cookies go, they were dry, not very sweet, and not very chocolatey. Each cookie was two chocolate wafers with some chocolate creme filling in between, but there was so little chocolate flavor that I wondered if they were just dyed brown. I gave them out to co-workers, and no one asked for seconds.
