I'm not a big fan of ESPN nor can I speak for Big River since I have never been there. I'm also not a big fan of Cape May; I personally think it is very "Golden Corral" in quality like every lunch/dinner buffet at WDW other than Boma. It offers mass made food made in advance and sitting on a serving station to be scooped up. I also was not impressed with the Crab Legs, they were no better than the local Chinese restaurant near me that offers the same quality crab legs. But one must take my opinion with a grain of sand, I am admittedly not a buffet fan at all. I will say that I did enjoy Captains Grill and found it to be a true hidden gem in WDW. The decor is nothing that stands out at all, but the food is very good, the dining room is quite and the service was good as well. Captains Grill is the only 1TS that I like on the Boardwalk. I am a big fan of the signature restaurants on the Boardwalk like Yachtsman Steakhouse, Flying Fish and Blue Zoo.
