We had a Greek pizza from Slice the other day. Not bad: artichoke hearts, olives, feta, onion. Anchovies optional. You know who opted for the anchovies. The pizza chef's had a judicious hand. The fish were't too few and they weren't so many as to overpower the rest of the pie.
I would be just as happy with a regular pie, double anchovy, but that's not what you get when you share.
