IMO, the character meals are all about the same when it comes to food quality. Good food and filling, but nothing out of this world spectacular. You have a character meal to interact with chracters. So, I would make your choice based on which characters you want to see as opposed to the food reviews. We ate at both places on our trip in May.
Park Fare was good, but I wouldn't go back there unless I had a child who really wanted to meet Cinderella and CRT was not an option. The food was fine, particulary the salmon, it's just that there are so many other WDW places I want to try. If we couldn't get those, than I would be just fine doing Park Fare again. Suzy and Perla visited each table multiples times, but Cinderella and Prince Charming came by once. The character interaction was nice, but they're in such high demand that they can only come by once.
LTT was a lot of fun. The food there was good, basically Thanksgiving with roast beef and ham as well. We experienced excellent service. Our server was very quick to refill our drinks and bring us more food when we needed it as well as provide us with some cheese when we requested it. I'm more likely to eat here again, but that's mostly because I like the characters better. Food was about the same, though I liked LTT a bit more. Goofy, Minnie, Pluto, and Chip & Dale(Mickey is NOT at this meal) visited our table multiple times compared with one visit from Cinderella and one from Prince Charming. They were lots of fun and played around with us a lot more than the characters did at Park Fare.
It's quite simple, as a Princess and Prince, Cinderella and Prince Charming must always be the royals that they are. On the other hand, Goofy & friends can play around a lot more because they don't have to worry about acting in an unregal manner. And Chip & Dale are great fun. They goof off so much, and are especially fun if you give them some peanuts. I think they visited us even more than the other characters did. I think I'll probably have to schedule one character meal per visit where they attend.
