I thought I posted about my stay a month ago, but I can't find any posts by me. Well in contrast to Zurich I was disappointed in the lounge in the evening, it was extremely crowded and boisterous, and there was basically nothing to eat except some undercooked cocktail sausages, and they wanted to kick everyone out at 2030.
Again opposite to Zurich I found breakfast in the restaurant to be quiet, and selection and quality above average for UK Hiltons, so if the lounge is continental only I made the right choice.
The room itself was fine with a nice view, but when I'm in Manchester I need to be near Piccadilly station so I think I'll continue to stay at the DT in the future unless rates are too high.
