Is that the one on Manchester? If it is, then there are 2 really close~ Mimi's Cafe and Millie's Restaurant. They're on Harbor, but closer to Manchester. If you walk down past the main crosswalk on Harbor(the 1 to take you into the parks) there's Tony Roma's. If you want to go into DTD, there's Napoli's(same as the 1 in Epcot), ESPN Zone (way better and a bigger selection than the one in WDW), Tortilla Joes (Mexican), Ralph Brennan's (New Orleans/Cajun/Creole), HOB, and Rainforest Cafe. There's also Catal, it's the restaurant that is right across from Uva Bar in the middle of DTD. They have a really good selection of food. I'm a big pasta snob, and I love their pasta.
Not sure what time you're coming in, but check in advance w/ what time the DTD restaurants are staying open to. The ones on Harbor should be open until at least 10, but w/ it being a Thursday and offseason, not sure how early DTD one's are open to.
I had a great experience at both Ralph's and Rainforest, but Tortilla Jo's, not so much. There's also the area... Gardenwalk, I think it's called? ... that has a large variety of restaurants as well.
