I can tell you from two experiences at Paddlefish, one lunch and one dinner ( you know for research in case it's different). Dinner does have more options of entrees, the options that are available at both times are the same price which is nice cause sometimes Disney likes to charge more at dinner for the same thing. With a reservation there should be little to no wait for you when you get there.
During the lunch trip we had the New England Clam Chowder and Lobster Corn Dogs to start. For our entrees we split the New England Seafood Boil and Fish Tacos. We skipped dessert at lunch.
For the dinner trip we skipped a starter and dove into the meal with Jambalaya and Swordfish. This time we did have dessert and we got the charred carrot cake and strawberry shortcake.
Both meals were great, I would go as far as saying fantastic but I would go back again and try more options. Honestly I enjoyed the decor when it was Fulton's a lot more but you aren't eating the decor, the food is still great and the service is great. But there is always room for improvement.
