Can't believe it took this long for somebody to mention Coral Reef. I like it more than any of the World Showcase options, though I realize that puts me firmly in the minority.
Next time I want a meal in World Showcase, I will try Via Napoli, if that means anything. Personally, I left Les Chefs de France, Tokyo Dining, Teppan Edo, Marrakesh and Akershus feeling pretty underwhelmed.
