The Wave (especially at breakfast) at the Contemporary, Splittsville at Disney Springs has great sushi and pizzas, Boma for either meal but my preference is breakfast, Sanaa (bread service alone is worth the trip), Olivia's at Old Key West, Wolfgang Puck Express at Disney Springs, Spice Road Table at Epcot, Liberty Tree Tavern in MK for lunch, not really hidden but we love Biergarten in Epcot. Also, don't give up, tons of places will open up as people change their plans especially at the 45 day mark. And honestly, I've never really considered O'hana worth the fuss.
