We certainly do not have as many cruises under our belt as others...but I have never noticed any *significant* difference in menus on formal nights. We sometimes do a specialty restaurant on a formal night, though.
You did not specifically say when your last cruise was...but I think you will find that *most* mainstream cruiselines have somewhat cut back on their food quality since the pandemic. They are all hurting for cash! But...food is VERY subjective, so you may have a different opinion, as might others.
