The Portugese custard tarts available at Casa Iberica on Johnston St are considered the best in Melbourne (at least according to The Culinary Club and Totally Addicted to Taste). As I have not yet tasted every tart in Melbourne, I cannot comment except to say they are wonderful. On a recent Saturday while walking past on the way to the city my girlfriend suddenly said that we must go in and get some, even though we had only had breakfast about and hour ago. I dared not disagree.
We entered and things immediately looked grim. Besides the queue ahead of us at the counter, we could hear a loud discussion in progress about the tarts. A woman had phoned in an order of 70, this had been misheard as 17, and there were not enough tarts when she came to pick them up. It seemed unlikely that there would be any left for us by the time we got to the front of the queue. We left quietly and vowed to get there earlier next time.
