I think the food at WCC is pretty typical Disney fare... nothing great, but not bad either. This isn't to imply anything negative, just that the food is "regular" stuff, nothing fancy or exotic, the type of fare you find at a good many restaurants both in and out of Disney.
WCC can be a lot of fun, but there are definitely "quieter" times when not much is going on. Lunch is one of these periods when not a whole lot of things happen. As the restaurant fills up, the antics quotient does too.
I would recommend trying WCC, not just for the WCC experience, which can be very entertaining, but also for an opportunity to explore the WL and vicinity. It's a great place to see.
Have a great trip!
