Well, if you're talking about just a good burger, forget all those recommendations that include toppings and stuff. The last burger I had at Le Cellier was awful, pure slop, but the last one I had at The Plaza was good. I like Raglan Road, but haven't had a burger there yet and am going to guess that it's really good like everything else there. I also like the burgers at Rain Forest. I don't do the dining plans so I don't know where that applies, but generally speaking the food is better at non-Disney restaurants like at Downtown Disney.
