Our family was celebrating a special birthday and picked Cassia for its excellent Chinese fusion food and nice ambience in Sentosa.
First off, there's a dress code because it's fine dining. However, most diners were in casual clothes. Then came the person who made the dining experience really weird.
The minute we sat down, the waitress brought the XO sauce in the little saucers and told my husband it's available for purchase. We had not even ordered yet so he didn't respond.
We then chose Chef Lee's Signature set. She asked if we wanted to pair with tea or wine. My tummy wasn't well and tea at night gives me insomnia so I opted out of both. The waitress recommended chrysanthemum. My husband asked if it was refillable and this was where her tone started to change.
Funny thing was we spoke English to her from the start but she always replied in Mandarin. We thought she couldn't speak English till a Caucasian couple to our right came and she spoke good English with them.
She served the courses with lightning speed. At one course, I was still eating when she brought the soup and stood next to me. I tried to finish quickly but she put the soup down and left. Won't the soup cool down?
My husband asked her for a refill of the XO sauce. She walked off and didn't come back. Earlier, when we were taking a family pix, she offered to take for us. We sat together and waited but she walked immediately to the next table and tended to a new diner. We waited but she never returned.
Then other wait stuff took over. It was a relief. We had the XO refill and we ate slowly.
At the end, she brought the bill and the coup de grace comment, "Wah, you can finish everything! We were speechless. Besides being there for the excellent food, the meal was $170 each. It was a celebration so we are willing to pay this amount. Why can't we finish the food????
Throughout the whole evening, we had the feeling of being put down. Is it because we were the only non-hotel guests and dressed for a celebration?
It was a sad experience in a beautiful place. The waitress said a birthday wish and also a Happy Vesak day, but I don't celebrate that. So it just added to the bad vibe although we tried our best to enjoy the time there. Our family has decided we won't ever go Cassia again. We had a good first experience but this second one will be remembered for a long time.
