On the red eyes from the west coast, SFO-LHR and LAX-LHR, they got rid of the cottage pie. It was explained to me that most people sleep. I did have the cottage pie on the return flight in November so at that time they were still available. There were no cottage pies available on my LAX-LHR flight last Friday (but in line with my understanding, although I always ask).

I believe removing the hot midflight snacks on the red eyes was one of the "enhancements" to Polaris announced last year.
