Budget
Samy's Curry
An old-school Singapore institution in an open-air colonial building, serving rice and curries on real banana leaves as ceiling fans whir. Waiters walk around with buckets of curry very cheap and take orders for tandoori, fish head curry and other treats which can be more expensive. No air-con, no reservations, no alcohol.
Thasevi Food
The original place for roti paratha Indian-style bread with curry dip, although the size of the portions has shrunk as their fame has grown. Still, most serves clock in at less than $2, and you can sample unorthodox variants like banana paratha or ice cream paratha, complete with whipped cream and chocolate sauce. Try the chicken murtabak and the Indian rojak. Halal.
Joo Siah Bak Kut Teh
One of Singapore's best-known joints for bak kut teh lit. "pork bone tea", a peppery pork rib broth. Two bowls, rice and a serve of mui choy veggies will set you back $9.10; add in $0.50 for some you tiow fritters from the shop next door to dip in your soup. Open from Tuesday to Saturday 8 AM to 8 PM, and to 3 PM only on Sunday.
Zhen Shan Mei Claypot Laksa
The best laksa in Singapore according to Makansutra and its many regulars. Expect to wait at least 30 minutes. Order with shrimp instead of cockles if raw shellfish is not your thing. Sold in sizes of $3/$4/$5.
Midrange
Marina Bistro
In the Raffles Marina at the extreme west of Singapore right next to Second Link bridge to Malaysia, offers very competent Singaporean and Western food. Try the excellent beef satay. Open to non-members for lunch and dinner daily; to get there, take exit 25 from the AYE, immediately before the Tuas checkpoint.
Canopy Garden Dining

Bollywood Veggies
Tucked away in rural Lim Chu Kang, this exuberantly colorful bistro with air-con and alfresco seating draws crowds on weekends with simple local dishes, made from fruits and vegetables grown on their backyard organic farm. The menu changes regularly, but favorites include their nasi lemak coconut rice, banana curry, desserts like kueh kosui coconut-brown sugar cake and home-brewed teas. Kids can romp around the farm, while adults can pick up organic fruits, veggies and herbs to go. All meat is halal, but the restaurant is not certified.
Zi Yean Food Centre
Locally famed outdoor coffee shop serving up Cantonese dishes like mui choy chicken stuffed with pickled veggies, prawns wrapped in tofu skin and deep-fried, kangkong with century eggs, and abalone with chicken a steal at $5/plate. Prices generally reasonable but some dishes can be expensive. Open for lunch and dinner, closed alternate Wednesdays.
Colbar
Stuck in the past and proud of it, this low-key eatery started life as a canteen for British soldiers, and fare like ox liver with peas and chips still figure prominently on the menu. Recently relocated complete with original building out of the way of an expressway, but still very popular. Try the famous curries if British grub isn't to your taste, and don't expect any frills like air-con.
The Olive
Fairly decent pizza and pasta in a very attractive setting in the lush greenery of Labrador Park.
Donna Carmela/Caipirinha
A family-run Brazilian churrascaria and an Italian restaurant with a vast array of pasta sharing the same premises, offering excellent home cooking in unpretentious surroundings. Their popularity is further cemented by the Italian wines they import direct and sell at retail prices from $25/bottle. Book ahead on weekends.
Top end
Casa Verde
Located right at the entrance of the Visitor Centre, offers a mixed menu of local and Italian food at slightly elevated prices, but this is still by far the cheapest and most casual place to eat in the Gardens. The best pick here is the large wood-fired pizzas from $20.
Chinese Box Restaurant
Located on the National University of Singapore Bukit Timah campus at the edge of the Gardens in a charming late colonial bungalow. The menu is pan-Chinese, the house special being Beijing duck $4 per portion or $68 for the whole duck, a northern Chinese dish not often seen in Singapore. All in all, competent but not out of the ordinary, and there's a small price premium for the location.
Beaulieu House Restaurant
On Singapore's northern coast, the restaurant is housed in a old colonial-style bungalow that is believed to have been built around 1910, and has sea views towards Johor. Both Western and Chinese food is served. Best reached by taxi.
Au Jardin Les Amis
Part of the "Les Amis" group of restaurants and situated in a restored 1920s residence in the Gardens. The food is mostly French with some other European dishes thrown in and many given a little Asian twist, but given the very high prices the quality is a little wobbly. There is a superb wine list and a very helpful sommelier on hand to answer questions. The views of the garden are gorgeous. Enter through the Corner House Gate and follow signs to Au Jardin/EJH Corner House the name of the building which houses the restaurant. Reservations recommended.
Margarita's
Popular eatery featuring reasonably authentic Mexican eats like enchiladas with mole poblano chocolate sauce and refried beans, washed down with their namesake margaritas. Fills up fast on weekends with expats out to satisfy their Tex-Mex cravings, so book ahead.
Halia Restaurant & Villa Halia
The location in the Ginger Garden of the Botanic Gardens is a reason in itself to visit especially at night, with stunning floodlit views of the surrounding jungle. The food is international with Asian twists, and while consistently excellent comes at a fairly steep price. To get there, enter the Gardens by the Tyersall Ave side entrance and walk a few minutes following the signs. Indoor and outdoor seating available, reservations recommended.
The Bukit Timah area to the west of the city is one of Singapore's poshest residential districts featuring many high-quality restaurants, particularly in the expatriate enclave of Holland Village (http://www.hollandvillage...). Another good option is Dempsey Hill (http://www.dempseyhill.com/), a convenient cluster of British-era army barracks converted into restaurants for the expat set, just ten minutes from Orchard Rd.
