Pre-Covid we loved it, ate there almost every morning since breakfast in park were high carb items. We had the build your own omelets and thought they were some of the best we had, defiantly better then others we had on property. They do offer a AAA discount but they auto charge gratuity no matter party size.

It’s been a while be we always found their classic breakfasts better than the quick service breakfasts at Disney resorts. And one was big enough for two, practically.
We have eaten at Picabu a number of times too when at the Dolphin although it has been a few years now, even walked over from the Boardwalk when staying in the villas. As the pp mentioned, the servings have always been generous.
