We disembarked Reflection 2 weeks ago. It was not among our favorite cruises with Celebrity but we put that down to our expectations regarding a New Year's cruise. (We did 2 in 2012 & 2013 but it was a different time on Celebrity.)
The only problem we had with the food was the buffet one day at lunch. Everything looked brown and spicy, which is harder for me to eat anymore. We didn't go back for lunch during the cruise. Breakfast was fine. We walked through one night and all the stations were open but this was before the change in evening offerings. We also enjoyed Luminae, Blu, Murano's, The Porch, Lawn Club Grill and Sushi on 5
As far as service, we boarded on NY Eve after a booked to capacity Christmas cruise. The first 2 days service was rushed but by the 3rd day things were back to normal. Our Butler told us she had 4 guests in our suite over Christmas.
We did not have a problem getting drinks at any of the bars we went to, even in the Solarium.
I hope you have a great cruise.
