loved Raglan Road (food, atmosphere, service & entertainment) but is expensive! And agree with previous poster....very fun for a noisy/party-type place but not for a relaxing meal. Do not recommend taking small children (babies/toddlers)due to noise levels & overall adult-partying atmosphere...every table in sight with small kids, the kids were crying...this was between 7:00 & 9:00 P.M.
Olivia's was very relaxing, great service too. We liked the food, and the desserts are very good.
Captain's Grill is good, too...good steaks, good service. Desserts not quite as good as most Disney restaurants (not bad desserts, just we had better at most other places.) Captain's Grill was also fairly relaxed & mostly quieter place, too.
Should be easy to get your choice of times at Olivia's or Captain's Grill...as non-park resort restaurants seems like they always have openings. Raglan Road can be a bit trickier, especially if you're going for a reservation during the time the live entertainment is happening. If you do go to Raglan Road, and don't have kids with you that a dying to eat I suggest you hold out for a table in the main room with the stage, well worth it...the singing group is great.
