Caesar salad must be the most bastardised of salads on earth - which is probably why many people have strong (negative) feelings about it. Like my husband. He doesn't like anchovies for starters and his first encounter with a CS was when he bought a sachet of it at some supermarket, unaware of what was in the marinade. He must have spat like a llama. But what can you expect of mass-produced salad sauces? It makes much more commercial sense to buy tinned anchovies in oil, you know, the endlessly salty variety that is as far removed from a real fish as Cadbury/Hershies/etc is from chocolate! Except for a sodium kick, I don't know why people even buy that stuff! No, what you want is the real thing: smooth silky anchovies in brine, bought from your local delicatessen (or supermarket, if you're lucky)... they do taste like fish and are a real pleasure to eat - I get cravings for them every once in a while where I could devour a whole tub full of them with some toasted Poilane bread - snack heaven! And of course, real parmesan, not the pre-grated version which, again, bears no resemblance to the original.
I didn't follow much of Gordon Ramsay's "Kitchen Hell" TV series, but I do remember him re-inventing a Caesar's salad at one particular establishment. I bought his book "Kitchen Heaven" a while ago and this is the first recipe I've tried - but the book is full of quite quick and easy recipes, some of which are even managable after a long day at work... so I tried the Caesar's salad some time last week and it was very yummy. My better half couldn't get enough of it! The fresh anchovies make all the difference of course, and I also loved the way he grills the bacon, then brushes it with maple syrup - it gives the salad a really interesting twist!
