What is ' chicken garlic chicken ' I was at a Brewers Fayre pub and saw this on the menu (pictured) 
When it arrived it was an egg on top of a garlic and breadcrumb chicken breast. Why call it chicken garlic chicken? The waitress didn't react in the slightest to the name, and it's still on the menu now 
Am I missing something here?
Purely conjecture but...

You've heard of chicken fried steak... right?
We also have chicken fried chicken... which is chicken prepared in the same way as chicken fried steak. It's different than "fried chicken " because it's a boneless (often pounded) piece of breast meat. 

It's amusingly recursive. 

So, based on the description on the menu, it sounds like a version of chicken fried chicken but with lots of garlic, so maybe they decided to replace the "scary" word, "fried" with the delicious word "garlic". 

Unfortunately this conjecture falls apart somewhat since chicken fried chicken is a staple of the southern US and the menu seems to be from a pub in England somewhere.
