Omelets in MDR and Johnny Rockets. However, I was able to get made to order omelets on Allure in the WJ in February.
FYI, prior to pandemic, the Oasis Class MDR for breakfast had a buffet breakfast with a made to order omelets stations along with many other breakfast items. This was in addition to the breakfast menu.
In addition to the luncheon menu, they offered a "Tutti" salad bar with waiters making salads at request, pasta stations, antipasti, etc. and some 7-9 hot dishes. Really enjoyed it.
