I was not impressed with the variety of the menu items in the 4 PC restaurants when reading them outside the dining rooms. I thought they would be changed daily, as the traditional is, but wrong, same food every day. I also was unaware that on 4 of the cruise nights, the menu from one of the PC restaurants was presented along with the traditional menu for the night. You can mix and match or pick anything from each menu. You get to eat the food in each of the 4 just as if you were there. To be fair, in the PC restaurants, you also receive the menu from the traditional for that night so you have the same food options no matter where you dine. We decided to try one of the PC restaurants just to see what it was like. We called a day in advance and had no trouble getting a table for 2 at 8pm, a time we like to dine. The seating was slightly more intimate but not what you would consider private. The way they have the 2 person tables arranged allows them to quickly put additional tables for 2, 4, 6, 8 etc into service as demanded. You are so close together, you make new friends whether you want to or not. The service was attentive but, to us, noticeably inferior to the traditional. One table is on the salad while another is on soup and a third on dessert. This is normal in a land restaurant, but the servers we had on the one night seemed to forget where we were in the process. Good servers but slow and forgotten requests. Maybe the opportunity of an extra gratuity provided some of the incentive for the outstanding attention we received in the traditional seating, but there is nothing wrong with that.
Another thing that one may want to consider, is that if you go with the PC dining, you are not allowed to change to traditional, while if you are in the traditional, you can opt out from time to time and return. We had a permanent drop out at our table and were joined one night by new friends of one party at our table. They told us that they were allowed to join us only because of the drop outs and because there were always 2 empty seats at our table. All in all on our next cruise, we will pick traditional seating again as we saw nothing to gain by picking the PC option. I guess if flexibility is most important, then traditional limits you somewhat but not enough to make a difference to us.
One bone I have to pick with Princess, is that the 'anytime' options on the traditional menu were disappointing to me. On our first Princess cruise last summer, they had a nice steak fillet that I could get anytime I didn't like the traditional menu choices. I picked that twice and the steaks were out of this world. Imagine my surprise when there was no fillet on this menu. I fact, there was no fillet on the Sterling steakhouse menu where we dined the one night. I don't know why Princess can have steaks loaded in Copenhagen, but not in L.A.
If there are any other questions about our cruise that I can answer, I'll try when I get the chance.
