Based on my terrible experience, I would say avoid this hotel at all costs. I stayed at the London Hilton Metropole recently and invited a friend for a full English breakfast. We both became very ill within hours of eating at the hotel with classic food poisoning symptoms. This was the only meal we ate together that day so was almost certainly caused by the breakfast we ate at the hotel.
I reported the case to the hotel management and they claimed to be investigating. After me chasing them for a response three weeks later, they informed me that they had performed a 'thorough investigation' and concluded that they were not responsible. Strangely, in the course of their three week investigation - they did not even contact my friend who had also come down with the same symptoms after eating us eating together at the hotel. How disappointing and how embarrassing for me who had invited someone to be my guest for breakfast.
In all, from the breakfast, to the customer service, to the not so 'thorough investigation' - a terrible experience. I will never stay at this hotel again. Be warned.
