I am not an adventurous eater (I don't like spicy things and I don't like a lot of flavours that are added to foods: simple and bland and a limited range of acceptable foods are my thing) and when combined with multiple severe food allergies, my dining choices are often rather limited.
But I really like the MDRs. I often eat off the "lighter fare" menu others have noted, and am quite content with a chicken breast or steak with steamed rice and steamed veggies, along with a soup and bread. Sometimes desert. My sister does likewise many nights and sometimes will venture into the kids menu.
Although I often have to do it because of allergies, if I don't want a sauce something comes with I will ask that it be left off or a substitute be used. I mix-up sides -- a side from one entree to go with a different entree.
We have sailed with Disney on 4 cruises and quite enjoyed our serving team each time. We spent time talking with them, they showed us how to do some of the tricks they do for adults and kids (we are two adults). Relaxing, enjoyable. Fancier than a home meal because of the setting, but not "fine dining" on the scale I am familiar with -- I have been to a very fancy, with a strict dress code (I actually had a buy a dress for it because I didn't have one suitable), restaurant with a fixed 7 course meal that has to be ordered in advance fancy restaurant before and quite honestly, thought it was a tremendous waste of money and certainly not worth the cost, though I am sure "foodies" would probably disagree; just THAT type of dining is NOT my thing at all. The MDRs are not like that IME.
Finally, a couple tips:
You can find copies of the menus online. This will give you a good idea of what to expect and what you might like to have or to try or to mix and match.
Once you are on the ship, if you have a smartphone or tablet with the
DCL app, you can go into it and actually view the menus for all the restaurants for the all the meals for the entire cruise. My sister and I spend some time our first day browsing the menus (since we then know our rotation) and seeing what we will be having where and such which helps us plan. If we know one night dinner will be kind of light, we may stop by late in the afternoon and getting a pizza or snack on the pool deck so we are not as hungry come late dinner.
Also, because of food allergies we actually order our meals after dinner for the next day, and that process goes SOOOO much faster if I have already looked everything up using the app -- I just have to glance at the menus the server gives me to confirm no changes and we can quickly place the order, instead of having to READ the menu and DECIDE among the options -- I have already spent my time doing that during the day or even during some of the downtime of dinner (yes we are that family that will bring our phones to dinner, but to do things like plan the next day together or check the next days menu, and we are both ok with that).
