Where isn't good for CS at Epcot? To us it's the 'oyster' of dining at Disney.
Germany, Sommerfest, is great! They have a Brat/kraut combo meal with AMAZING apple strudel.
Morocco is also very good, but not really worth the $$ if you're not on the
DDP. You get a lot of food, but I think $13+ is a lot to pay for the food. It's good, but not $13 to me (IMO) On the DDP? Go for it!! It's worth the credit!
Sunshine Seasons has a great variety, ok quality, and it's nice to have several different types of cuisine in one location. They also have nice desserts (if you're on the DDP and getting a dessert) It can be pretty loud due to its location, but it's worth a visit.
Cantina is pretty good, but beware that it can be almost impossible to special order there. My funniest story about Cantina is when I ordered nachos without beans. She said she couldn't do a special order, but the beans were on the side. I said "fine" and got the nachos. "Side" meant "Top Side" and the nachos were buried in beans!

Live and learn. The chicken tacos there are great though, and I recommend them.
