Just to clarify; This thread and conversation is about Cabanas
dinner.
OP; Yes we eat there once a sailing on average. We do enjoy it. And yes, that is exactly why we eat there, to avoid the MDR's. ... (MDR - main dining room)
Or to have a fresh made steak.
But it comes with caveats. See below.
Cabanas is a great option for those interested in avoiding the MDR's for whatever reason.
They do ask for the KTTW entering Cabanas when dining just for data analysis purposes.
I suppose you could resist, and claim privacy rights. But .... if you are hungry ....
Never seen Cabanas dinner Menu on the Navigator App.
You can ask that day aboard the menu options for that night.
Tell the Hostess you are on recon and they won't scan the card.
As previously noted, Cabanas is not available first and last night for dinner.
You need no reservations for a Cabana dinner.
Cabanas does have operating hours though unfortunately.
They may vary nighty too.
It is definitely quieter than the MDR's. By a huge margin.
You can actually hear your table mate(s) speak during dinner as PP mentioned. This is priceless IMO.
They space groups out early, when possible. Spreading the whole crowd out.
Last time we had 18 pax. lol. But word is getting out. So , .....
It usually is must faster than the MDR , and if requested, can be super fast service.
Table spacing is at least double or quadruple MDR.
Tips are not expected. Trust me. Have ate there umpteen times, left tip once.
They will of course take your cash.
You can also ask for a slip/printed receipt to add tip to onboard account.
If you abandon your MDR servers for a night, it is proper etiquette to alert them prior.
You can call on any ship phone.
They will be waiting for you in the MDR. If you don't show, they may call you.

That can be embarrassing.
Often there are many choices for tables in Cabanas.
Early they block one side of Cabanas. If enough folk show they may open other side of Cabanas.
Never seen that happen. Heard of it happening though.
Cabanas is a training restaurant for new hires as previously noted. We have had mixed experience with this.
Sometimes they're overbearing to prove themselves to the pax, supervisors. ? ? ?
Sometimes they are laid back and possibly less engaging than expected.
My recommendation is speak up, and tell them how you would like the evening to progress.
That is what we have done all but once. Perhaps we learned the first time? ? ?
I don't recall if it was the first time that made me speak up thereafter. It could have been.
If you say nothing, they will continue with there pre rehearsed, patented expose.

Which may not fit your families expectations. So speak up and tell them what you like. imo
Although after all these years, sometimes it is just fun to watch the new trainees perform.
If server is over performing the magic, in your kid face, speak up. Etc.
As mentioned up thread, steaks are prepared onsite. As PP noted, and I agree, the best steak I have ever had aboard was in Cabanas at night. .... Repeatedly, over many sailings. .......... Rib-eye and NY-strip.
As mentioned, tips are not expected.
I only left a tip once when every thing flowed perfectly, and the servers were more intuitive the down below in the MDR.
They "worked" the kids and adults perfectly thru all courses, etc. Read the crowd perfectly.
Of course I was cashless, so I asked for a printed receipt, to apply a tip to those servers in Cabanas.
Yes, I asked if that receipt tip would apply just to them, and they said yes.
And I can confirm there is no shifting of tips from the general tips, away from the room stewards, etc. to any specialty restaurant, including Cabanas, Remy, or Palo regardless of where you may eat.
I can confirm, as PP, the general tip fund, does not go to Cabana folk.
But again, they do not expect a tip. They know this, and deal with no tips daily.
Cabanas used to always have a great salad bar, but that seems random lately.

I know many yearn for fresh salad. We often struggle at sea to find a great salad.
We have a 68 % success rate for salad aboard. Just an estimate fwiw.
You can just walk in and do recon, check salad bar, tables, waiters, etc. in Cabanas.
Then walk out. Don't be shy. Oh, take a salad too, if available.
You must at least check it out even after dinner in MDR. Or perhaps prior.
BTW. You can always walk in and get a salad and walk out. Yes. Salad is free aboard, if you can find it. lol
Yes. A couple salad freaks here.
We often have to make salad at the pool food stations.
Lettuce, tomato, olives, pickles, onions, etc. Brought our own dressing. Occasionally our own croutons.
I know it's scary.
TSA stole our salad dressing once. It was devastating.
We hope they don't ban salad ingredients, or we will book another cruise line.
Rant over.
