Thanks for all the responses! Now I've just got to narrow it down! My family is really flexible when it comes to food, so we're open to any of the Epcot restaurants. We've done Biergarten before and loved it, but my parents want to try somewhere different this time. I'd say I'm leaning toward Via Napoli, but I'm also intrigued by the Garden Grill (since they source some of their food from The Land Pavilion itself) and the Coral Reef because of the setting.
We already have ADRs at Chefs de France and La Hacienda de San Angel (margaritas!!).
