We're not star class but have eaten at Chef's table on Anthem, as well as other ships. Love it, though once a cruise is fine. And yes we speak to someone at Chops, at least 1 day before, to pass on our food issues. We always confirm when we arrive that evening I don’t eat anything that comes from the water. Dh doesn't eat shellfish or meat. They are always very gracious about accommodating our issues. Remember this is a set menu, 6 courses including dessert with wine pairings. New Year's Eve on the Jewel 2021-2022, with only 9 of us, spent 4 hrs there, told it's not the record for longest evening. Great evening. Most evenings run 2-3 hours. Enjoy.
