Input: BK is always my favorite fast food joint. Had lunch here before catching my flight to Denver.

I ordered the BK Big Fish sandwich - with cheese and onions added. For some reason the BK Big Fish was not listed on the menu - so I asked first.

They had three cashiers working the line and they were moving it quickly. And the expediter was cranking out the food to hungry customers rapid-fire.

The sandwich must have just come out of the fryer, Hot, crisp, cheese was melted, and oh so damn tasty!
