Mosaic in City of London, Westminster

Enjoyed a lovely meal here after a fantastic spa day. My friend had the traditional and I had the vegan afternoon tea. Both were fabulous. The lemon curd for the scones was perfection. Was as happy with my vegan options as she was, in fact I liked mine better! The sandwiches were all flavoured really well and the service was great. The ambiance is a lil clinical but would definitely come back again.

Really enjoyed the half-meal options in their Eat Well menu. Perfect for a pre- or post- workout meal. The set menu that they offer for dinner is great value, as it comes with house wine and soft drinks and considering the location of the restaurant. Only gripe is the unusually expensive coffee (£6++)!

A little sterile but the food was good and they do half healthy portions which is a great idea

Let me preface this by saying we are Americans and maybe have a little different expectations for a high end restaurant that is this expensive. The food was absolutely bland and not to mention the portions were unbelievably tiny. Keeping in mind we have larger portions in the US this was just mockery of our dinner. I won't comment on the rest of my family's meal but my Rack of Lamb was not only not a rack but as you will see in the picture but it was about 60% fat. All in all overpriced and I would never eat here again.

The food is absolutely deliciously !! Price is so reasonable !!

On the fourth floor of the Westin Hotel, the food is good and the service is also very good. At the end of the menu, there are half-portion meals for guests who don’t want too big a portion. There are two prices for afternoon tea, 45 and 50. The 50 price comes with a glass of wine. Plus 12.5% ​​service charge. You don’t need to tip extra, of course you can tip more if you want.

Disappointing afternoon tea. Staff had no knowledge of what they were serving us. Food was just left on the table without explaining what is what

Terrible service and food. Soup was bland. Sandwich came with a salad that had a lump of mud in it. Nobody asked how my meal was. When I complained they took it away, and still wanted to charge full price. Ridiculous!

A nice little restaurant. Service staff were polite and really tried hard to provide the right level of service but unfortunately fell short of what you'd expect from an establishemnt like this. Food, however, was very good. Both the Christmas menu and the normal menu meals were well proportioned and generally good value, based on London prices.

Very nice restaurant, thanks to Mr Neel for great service in 2 languages!

I’d definetely recommend this restaurant. The service was amazing. Nikola took good care of us and he deserves over 5 stars. The food was also delicious and not even expensive.

£45 pax for afternoon tea (without bubbles) and no complimentary refills on any of the food. Most decent hotels do refills, especially if they are 5-star. Not surprised as Westin’s parent company, Marriott, is American - they will “nickel and dime” you. Hope this strategy is reconsidered.

Solid restaurant inside the Westin. I had 2 brealfasts, a lunch and 2 dinners there during my stay this week. Service from the staff is friendly and efficient. Two of the meals, the food came out excruciatingly slow and one meal my steak was way undercooked. The breakfast buffet is plentiful was a good selection. I enjoyed the food and experience.
