It amazes me that so many people can have such differing opinions of the same place. I'm sure it has much to do with the kind of food you are used to.
We ate at both places within days of each other in September. Of the two, Cap'n Jacks was the better for me. A brief wine-fueled review of each:
We ate at Cap'n Jacks on arrival day. We were starved.
We ordered (and sampled each others):
Appetizers:
Crab cakes: Hands-down the best I have ever had. They were tender and crunchy and the flavor was out-of-this-world.
Shrimp cocktail: Very fresh, huge meaty shrimp. Very good.
Mixed green salad: We were at WDW, on the Dining plan, and the chick ordered a salad...it was a salad!
Entrees:
Twin lobster tails: Smallish, but tender and sweet. The sides were also good.
Very impressed, considering we were on the DDP.
Chicken Alfredo: Very good as well. Rich sauce, nicely herbed.
Desserts:
White Choc Raspberry Cheesecake: Very yummy.
Double Choc cake with ice cream: OMG. I am the idiot that ordered cheesecake, and I coveted the other two's desserts.
Drinks:
Blue Glowtini: Pretty good.
Fuzzy Captain: WOW. Just Wow.
Service: Seated immediately and the server showed up every time we needed something.
Raglan Road:
Soda Bread with Dipping Oil: Very tasty.
Appetizers:
Drunk Chicken: Good but not great.
Scallop Forest: Scallops were not as hot as they could have been and a little (just a little) soggy.
Dalkey Duo: Excellent!!! Worth going back for!
Entrees:
Kevin's Heavenly Ham: Good. Interesting flavor.
Paddy's Pork: didn't care for the stuffing.
Serious Sirloin: A bit tough and a little gristly. Subbed Colcannon for the mashed potatoes and I wasn't impressed, but as I said I am from the midwest so used to cabbage cooked in bacon. Disappointed with my entree.
Dessert:
Gar's Bread Pudding: Think of the best sex you ever had (sorry). This was better. We all got it, thank goodness, as none of us would have shared.
Service: waited 20 minutes in a drizzle to be seated, though there were plenty of tables empty. Server showed up about ten minutes after we needed him, every time.
Of the two, CJ was the favorite, though I will probably revisit RR just for the bread pudding.
