Yes but a relatively innocuous reference to common cuisine items isn't racist. If I said "you've been a naughty boy, syrian scholes, no hummus for you tonight!" there's not much wrong with that because it's a reasonable and non-discriminatory assumption that you might eat hummus a lot seeing as people from a particular place or region tend to favour their own cuisine. But if I were to make a derogatory remark about parts of your anatomy and substituted 'halabi kofta' for said anatomy, that's a different story.
For what it's worth, I think the Park lyrics are on the racist side of things but can understand the choice as it's a comparative reference of one food item being worse than another (rats worse than dog meat) so a more innocuous choice like Kim-Chee wouldn't be suitable for the chant because the comparison is less like-for-like and wouldn't be as insulting to Scousers. Let's compare, (alternate in-offensive lyrics in brackets):
Park, Park, wherever you may be
You eat dogs in your home country (You like to eat lots of spicy Kim-Chee)
It could be worse, you could be Scouse
Eating rats in a council house (Eating boiled cabbage in a council house)
