You're right in that you can't please 'em all and Kostas equally has it's supporters. We eat, not only, at both but also many others. At Brouklis, I love to munch, not only on the spit lamb but also the chops and they do a very mean steak.
Equally Kostas and all the local Tavernas etc, have their regulars and, for whatever reason, a disappointment of anyone will bring in, I'm sure, bags of support for someone else's favourite.
But, you enjoyed your holiday and that's the name of the game.
It would be good if maybe you shared your activity Holiday with all as it may give other Forum members ideas of where to explore.
( We live here and are still finding places!)
I'm sure you will get a lot of advice on Corfu Airport. I would suggest that if you are flight only then pre-book the seat or, if with a package deal, get a taxi back, not forgetting to let your Rep know.
