Yes, it is shown in a few episodes (the first being "Showdown at Dark City") that Pikachu likes ketchup.

In my opinion, I like Pikachu, but it isn't one of my favorites, due to its major popularity. Many fans love Pikachu and it can also be clearly shown by countless of people. I even met non-Pokemon fans like Pikachu, because it is really well-known.
The things is, Pikachu is not only a Japanese mascot, It's a Mexican slang term of endearment between on vato to another. It's like "Oye Pikachu, Donde andas guey." "Dale Pikachu! No seas pendejo!"
