Awesome hotel restaurant! I was stuck because of a canceled flight, but Joseph completely took the stress away. Huge shoutout to him—super welcoming, went out of his way to help us, and made us feel right at home. Great food and such a cozy vibe!

We had a wonderful staycation at Aloft Singapore Novena. The hotel was clean, modern, and comfortable, making it a great place to relax and unwind. A special thank you to Olivia, who took such great care of us during our buffet breakfast. She was warm, friendly, attentive, and always greeted us with a genuine smile. Her excellent service made our breakfast experience even more enjoyable and truly stood out. Thank you, Olivia, and the entire team, for your outstanding hospitality. We had a memorable stay and will definitely be back. Highly recommended!

On Thursday, May 7, our group of 11 had a great Mother’s Day lunch at 21 on Rajah, Thai buffet. The food was delicious, the spread was just right, and the service was excellent. Prices were reasonable too, especially with the senior promo. Thank you and we’ll be back soon!

Cooked food spread is alright. But good value especially with the one for one lunch deals. They charge for still water. But you dont really need this since they've a wide range of teas and coffee options. Dessert soread is good too with pastries and fruits and a fondue
