Maribel (who served us) was EXCELLENT. Attentive yet knowing when to leave us to talk. Please pass the feedback on and reward her if possible. We will return based on this.

Difficult to find on the 4th floor of the westin marriott. The food was good and value ok for the set menu. But the service was not great- helpful but needed reminding a lot.

Unfortunately, we booked for an afternoon tea on Wed 14th Aug @3.30. We received confirmation from you with address of 60 Upper Thames Street with contact number as well. Despite walking the length of Upper Thames Street, using google maps, asking people the restaurant appeared to not exist

The reviews on this oversold it quite a bit, the food and drinks were good but it was empty on a Thursday night.

When you find the restaurant (in the Marriott Hotel, on the fourth floor) you feel like you're approaching a 5 star spa. The smells, cleanliness and decor is all very engaging. The restaurant itself is relatively minimal and elegant, mainly round tables throughout. Views to the Sky Garden in the distance. We opted for the set menu - two courses from a choice of three with the option of a third, plus a glass of wine or non-alcoholic drink as part of the deal. The starter was plentiful and full of flavour, the staff super attentive and accommodating. The main course however was quite possibly the best salmon - cooked to perfection. We didn't opt for the desert as the food, the bread basket, and drink was just the right amount. Definitely a recommended venue, for small groups, business, or even romantic evenings.
