It is very quiet in the afternoon during the week - which is lovely if you're looking to escape the crowds at other attractions. That said, the half dozen or so customers meant the bar tender opted to take a long break. We went looking for someone twice to order drinks, and then again to close our tab when we were ready to leave. If you're fairly self sufficient and looking for a space with views to nap/have a conversation, I would recommend it.

Found this rooftop bar as I was trying to find a place to chill, read a book and catch the sunset. Staff were nice and accommodating. I had an appetiser and a mocktail, which was alright. The view and sunset was worth it! Visiting on a Tuesday at 5.30pm till sunset meant the setting was a little bit more peaceful. Thank you to staff member, Angel, who was great at engaging customers in conversation. Her energy was very sincere and joyful, which made the experience just like the sunset – warm and colourful.

Thank you Raj and his team for making the experience at this restaurant such a great one. It rained before we got here but still wanted to enjoy the view so they escorted us to seats which were waterproof so we still had an enjoyable experience. Raj specially helped me to have more drinks option as I couldn’t really take sugar so he specially made and adjusted the lime juice in the drink asam boi. Thank you for the great experience. The fish skin we had were also really crispy. The first time we were there we had nachos which were really good as well. Was our second time there, great place to chat with friends and enjoy the scenery. Thank you!

Sad we missed the coastal feast but was satisfied with the festive feast. All the items served were excellent. Turkey breast wasn't dry and fish was juicy and tender. The 1-altitude coast chicken wings and drums paired well with their house sauce, which i recommend with the fries as well

I attended a wedding banquet at this rooftop bar and restaurant located in the Outpost Hotel, Sentosa, and while the setting was beautiful, the overall experience was a mix of good and bad moments. First, it’s important to note that the restaurant is not directly accessible from the main hotel lobby. You actually need to use a separate lift lobby located across the carpark to reach it, which can be a little confusing for first-time visitors. Once you arrive, the view from the bar area is stunning. It overlooks the entire stretch of beach below, offering a breathtaking panorama that’s perfect for photos or sunset drinks. There’s also an infinity pool located next to the bar, which adds to the scenic atmosphere. However, the layout feels slightly unsafe, as the sofa seating is positioned right next to the pool’s edge, leaving very little space to move around — something to be cautious about, especially during crowded events. As for the wedding banquet, the food service was quite slow, which is somewhat expected for large events. However, what stood out was the uneven timing between tables. While about two-thirds of the guests finished their main course for more than 15 minutes, the remaining third were still waiting for their dishes to arrive. This inconsistency disrupted the dining flow and made the experience less enjoyable. The service quality also varied. One of the staff members serving our section was particularly unresponsive — when we asked her a question, she did not reply and simply walked away, leaving us unsure whether she understood our request. Two out of three times she didn’t bring what we asked for, which became quite frustrating. Eventually, we decided to approach another staff member, who was thankfully much more helpful and attentive.
