I did the Blue Bayou package and was pleased. (I know it's not the one you're looking at, but it's another option.) The food was the regular menu food. My seat was awesome! It wasn't really that much more expensive than a regular dinner there would be. I was happy I did it. I chose that package because I knew I was going to eat dinner at Blue Bayou on that day already--it was worth the few extra dollars to get a decent seat for Fantasmic! at the same time.
As for your specific questions, the location for RBT also looked pretty darn good; it's just to the side of the Blue Bayou seating (which is pretty much dead center). So, doing the package would get you a good seat.
To me, "worth the price" is relative. Most of the food in the parks is probably not "worth the price" by other standards. So the value isn't necessarily in the food. Are you going to eat an overpriced dinner in the parks anyway? Is it worth it to not have to stand in a less-than-ideal location? Or to have to worry about getting a FP at some earlier point in the day? If the answer to those questions is "yes," then it's probably worth it, even if the food isn't great.
If you're that worried about the food, then consider the Blue Bayou. I think it's another $19 per person, but the ambiance is better and the food I had was quite good.
