We were just there last week as a matter of fact and yes, I had the twin lobster tails. It was ok. Yes it was covered on our dining plan. My Dh and I were totally disappointed with Capt Jack and will not be returning any time soon. First, for what I perceived to be a seafood restaurant, they had barely any seafood. In fact, aside from the lobster, there was only salmon.There are no advance priority seating so you have to leave your name. We had to wait approximately 2 1/2 hrs on a Wed nite. With the lobster you get some carrots and bland rice pilaf.
I have eaten in many Disney restaurants and this was really at the bottom.
