The food courts at Central World (if you can tolerate the place, I always liked the one on the top floor, particularly for Lad Nah at around 60 THB) and Central Embassy and the centers in between them are all much better that the food court at Paragon, though the food in the high end supermarket is interesting at Paragon. Not cheap though .. it;s a high end mall.

You could make for a nice food/drink crawl from Central World to Central Embassy. I think the one upstairs in Central Chidlom is a real treat. Again, it's not cheap, if you want cheap, you might try the one at T21.
