I can't help you much with how many credits per place, but I can tell you some of the non-park restaurants that we've enjoyed.
YSH is really quite nice. We've always had excellent food there and good service. Ricardo, a server there will provide you with incredible service.
Cape May Cafe is a great buffet for a group with widely divergent tastes. There truly is something for everyone. The Cape May Character Breakfast Buffet is really nice too. :yes: Lots of character interaction and a very nice selection on the buffet.
We hated the Yacht Club Galley, by the way.
Spoodle's is ok. It's gone downhill like a stone since it's stellar beginnings but it's still ok.
Boma, of course seems to be a favorite, although we prefer Jiko.
We don't much care for Chef Mickey's but did enjoy 1900 Park Fare.
We did NOT like Narcoosee's food and dreadful service!
Beaches and Cream is loads of fun, and is one table service credit (I overheard that when there once). Great place for burgers and ice cream.
Oh, last I knew Raglan Road took
DDP. Nice place if you choose the right menu item. Do NOT choose fish and chips from there. Get those from Cooke's of Dublin. Hotter and fresher.
The Turf Room is one of the best kept secrets on property.
We're the odd two who have had three very decent dinners at Boatwright's.
We didn't care for the Wave at all... California Grill is nice, but I think that's 2 credits?
WL has Artist Point and that is one of our favorite places. Whispering Canyon is also there. We don't much care for it, but loads of folks do.
We've been really disappointed with Kona Cafe and 'Ohana this year, but others seem to be happy with those restaurants.
Olivia's at OKW is decent enough for a non-fancy meal. If you are looking for a quiet place to have dinner or lunch you may want to try there.
We didn't care for breakfast at the full service restaurant in CSR (the name escapes me right now).
That's all I can remember right now. I'm not a fan of the DDP, having only used it for one visit and had the absolute worst experience with it, so I'm not the best to advise you.
We do (well, before the advent of DDP and subsequent fall in service and food quality) or rather we did like to dine with Disney quite often.
