Amazing Breakfast Experience
When we come to London we love to stay at the Westin. My favourite part of each stay is breakfast at Mosaic. The staff is attentive, which is always helpful when you have small children. They have a buffet, along with plated options and an omelette station. It is always a fantastic meal, but the staff are the best part. In the afternoon, this is a great spot for tea and champagne. Will definitely go back on my next London visit.

Breakfast and service

I thoroughly enjoyed the breakfast at the Westin. I was warmly welcomed by Pyush with a smile and a gracious gesture, and guided to the breakfast area, which offered an excellent variety and selection. Pradhuvav was exceptionally hospitable and respectful. The entire team was wonderful—there was truly nothing more I could have asked for.

Amazing food and amazing service by Alejandro and Maribel at this cosy restaurant. Will come back!!! The Korean chicken, burger, harissa squash and cocktails were all delicious.
