I think Ragland Road and Wolfgang Puck cafe are both quite a bit better than Captain Jacks. I don't know what you're looking for but I wouldn't consider any of those three particularly romantic. Ragland Road is very fun -- but extremely noisy when the band & dancer are there. (Might not be earlier in the day/evening.)
If you're dining at Downtown Disney simply to avoid having to eat somewhere that requires park admission you might consider some of the restaurants at the resort hotels. There are a variety of great choices. My favorites are Kona Cafe in the Polynesian and Grand Floridian Cafe at GF, there are lots more that sound wonderful too. You could also consider the signature dining restaurants which sound fantastic but they do take 2 credits on the dining plan.
