Is that a Bird's Eye fish finger or a battered one? The Swan fish fingers are battered.
Getting away from the Swan (fleetingly), there's a pub in Aylesbury that does a fish finger, cheese and bacon sandwich. Sounded bizarre and horrid to me, but perhaps you'd like it? (I presume someone does, or they wouldn't print it on the menu.)
If it's a bird's eye fish finger with bacon and cheese in a sandwich then I'd eat it..... yum yum.
