We just spent 5 NTS there, last leg of our 3 way split stay.
Breakfast at sanaa is quick service, but there can be long lines in the mornings. DH tried twice our first morning, line too long first time, second time it was short but the person taking orders also made the fancy coffee drinks, so it was taking too long. He was successful another day in getting breakfast though. We bought a box of entemanns cinnamon rolls from the shop and a fruit cup for other breakfasts.
The pool bar is open for quick service...never ventured there though, so not sure of the hours or menu other than what is listed on the app.
We had an ADR for Sanaa one night, so we had dinner there once. Had food at the parks other days or got food from the kidani shop fridge. The fridge in the shop had 2 types of salad--tandoori chicken Caesar, or a harvest salad with chickpeas, and a couple sandwiches--turkey club with bacon and arugula on multigrain bread and a curried tuna salad croissant sandwich. We tried all of those and they were yummy. They also sell deli meats, a cheese/salami/cracker thing, celery/carrots/ranch dip, fruit cup, grapes, and frozen foods like pizza if you have an oven. They also sell zebra domes in the shop!
There is no place at Kidani for burgers/fries.. We didn't attempt to do the takeout option at sanaa after reading some of the stories of long waits on the boards.
