Wonderful birthday meal that I was treated to here. Opted for the Thai part of the restaurant and was not disappointed. Highly recommend for spice lovers! Service was extremely attentive - almost too much so at some points, sometimes dishes felt slightly rushed but this did not detract at all from quality of food and service.

Highlights: satay, crispy squid, beef, spicy papaya salad.

Will definitely come back.

Great Asian restaurant, nice receptionist, fast, pleasant and attentive service, food was very delicious, for appetizers the crispy squid, pomelo salad & prawn cakes so tasty just the spring rolls , chicken satay & escargot’s the taste was average and we ask for extra roti and the waiter bring it right away without any additional expense.
The crispy seabass  was great and must try as well the king prawns pad thai, the lamp chunk curry was so tender but I didn’t like the curry gravy too much.
Passion fruit panna cotta & sticky rice with mango was so tasty
Overall, it was a great experience, the service was excellent, and the restaurant is worth trying. I highly recommend it and will visit again.
