Budget
Seah Im Food Centre
Popular with locals, has a range of Indian Muslim food stalls and a variety of local cuisine. The building is rather old, but the food is quite good.
Food Republic VivoCity
Themed like a collection of 1960s hawkers, only with air-conditioning and hygiene. Slightly expensive for a food court, but the selection is good and it's usually packed.
Koufu
The only foodcourt on Sentosa with the local food found in any run of the mill foodcourt. Food prices are ridiculously priced compared to mainland prices. Food all right, but there are tastier options around.
Midrange
Thanying
A branch of the well-known Thai restaurant at Amara Hotel in Tanjong Pagar. Best known for their duck curry with pineapple and longan.
Trapizza
Offers the improbable combination of pizzas, pastas and a trapeze school.
Sakae Sushi
Beachside conveyor belt sushi yes, with aircon, hardly gourmet fare but quite tasty anyway.
Top end
Barnacles Restaurant & Bar
Mildly over-the-top beachside restaurant complete with rippling waves projected onto the ceiling. Competent if not cheap Mediterranean and Chinese seafood dishes and grills. Terrace and outdoor seating. Free parking and they'll even reimburse your Sentosa entrance fee.
The Cliff
In sight of jungle, beach and sea, repeatedly voted the most romantic restaurant in Singapore and popular with bosses out for a naughty night with their secretaries. Book a table on the lower deck for the best views.
Il Lido
Modern, stylish Italian restaurant with indoor and outdoor seating, featuring views of the Straits. Bar-lounge with live DJ attached. Some dishes are excellent try the spaghetti with sea urchin or the seabass with porcini, but for the very high price the quality is rather uneven.
Jewel Box
On a hill opposite Sentosa, accessible via the cable car, the Jewel Box is an assemblage of three fancy, pricy and generally unspectacular restaurants Empress Jade, Sapphire and Black Opal, but the rooftop Moonstone bar is a good place to just go for a drink and watch the lights twinkle.
kunio tokuoka
The very first overseas venture by 4-star Michelin chef Kunio Tokuoka, who is a leading culinary maestro in Kyoto, Japan and grandson to the founder of the famous Kitcho. Located at level 2 of Crockfords Tower with easy accessibility from FestiveWalk, kunio tokuoka offers Japanese haute cuisine that extends far beyond the flavour of the food and its presentation on the plate.
As you might expect from a giant amusement park, food on Sentosa is by Singaporean standards rather pricey and mediocre. Things have, however, gotten slightly better in recent years with local chains allowed to open up outlets. For cheaper food options try either VivoCity or HarbourFront Centre.
