Whoops! The sign in front of this shop in the basement of United Square is implying that healthy Korean food is usually not delicious. I mean, okay, maybe, but that’s not what you want people to be thinking when they’re standing in front of your Korean restaurant at lunchtime.
What if they used “and” instead?
Healthy and delicious Korean food
Well, now it almost sounds as if they’re offering two different kinds of food, healthy Korean food and delicious Korean food, which still implies that “healthy” and “delicious” are incompatible.
They should just put the two problem adjectives in front of Korean with just a comma:
Healthy, delicious Korean food
The reverse order sounds okay too:
Delicious, healthy Korean food
