For ___ and giggles, I went to CC to find some Royal menus of late (as of 2018) - here's what we've got:
Day 1: horseradish crusted salmon, spicy grilled pork chop, aged prime rib, chicken marsala, baked polenta and feta, fish of the day, NY strip loin
Day 2: seafood linguini, almond crusted cod, duck a l'orange, pork shank, roasted beef tenderloin, veg casserole, fish of the day, roasted chicken breast
Day 3: braised beef short rib, lasagna al forno, chicken cordon bleu, wild mushroom risotto, fish of the day, grilled chicken breast, NY strip loin, spaghetti bolognese
Day 4: garlic tiger shrimps, roasted rack of lamb, chicken parmigiana, steak diane, tagliatelle, fish of the day, spaghetti bolognese
Day 5: pan seared wahoo, broiled lobster tail, slow roasted prime rib, potato gnocchi, cheese tortelloni, fish of the day, grilled chicken breast, NY strip loin
So definitely not only 2 new entrees every day, and to me it seems more like about 4 new entrees every day which SEEMS to be similar to what
DCL offers. In any event, I didn't find DCL food amazing in the MDR and I doubt I've ever said that about any cruiseline MDR. But I could pick something from each of the above menus and I'm sure I'd be reasonably satisfied.
Edit: for appies, I can see that they offer 3 new appies every night with 5 mainstays (baked french onion soup, caesar salad, escargot, shrimp cocktail, fruit medley)
