We are Gold on Regent and Silver on Oceania. Been on both in the last 9 months.
Regent Splendor,17 nites: Not one bad meal in Compass Rose. Had the best steak ever on R or O in Prime 7. Excellent food in Pacific Rim plus they had a very good sake selection. Although Chartreuse is our least favorite, the one visit we had was excellent. Sette Mari also very good both times.
Oceania Riviera, 18 nites: The BEST thing about O is The Terrace. Not having to dress after a long day touring is priceless plus the food selection hits all the right notes. We never go to the GDR as we are not fans of 2 1/2 hour long meals. Jacques, Toscana, and Red Ginger all were excellent. Polo once again failed epically; slow service, steak not cooked as ordered. No clue as to why this one venue just can't get it right. Waves pizza in the evening was a nice change of pace especially since you can pair its with whatever from The Terrace.
Bottom line, we did notice a few cutbacks, typically at breakfast and lunch, on both lines. But in general the food was still better than the mass market lines. I wish O could deliver the same type of experience as Compass Rose and wish R had a casual venue in the evening ( like the Pool Grill) where you didn't have to dress, however.
