Carriages are usually quite clean and of reasonable condition. Buffet cart is poor though - limited range of sandwiches and especially poor for breakfast. The only healthy option is porridge which is good but often this is out of stock. The bacon sandwiches etc are dreadful as the whole thing goes in the microwave which makes the bread soggy. The packs of sandwiches sometimes also have soggy bread. I have taken them back before and got my money back. Good that wifi is available for all - very important to have - although it is a bit hit and miss. Train is usually very busy at peak times - desperately needs another carriage.
