Ok! So here's a rough food guide to Singapore. If you google "Singapore Delicacies", you'll definitely find alot of guides. I'm just going to attach a list here and highlight a few of my favorite: Singapore food guide
Bak Kut Teh: Song Fa is the restaurant that I'm familiar with, with multiple chains all over Singapore. The problem is that at times, the soup can be too peppery. Another alternative that I like is Old Street Bak Kut Teh, which has a few chains all over Singapore too.
Wanton Mee: Best eaten slightly spicy with pickled green chilli on the side. Pontian has multiple chains all over Singapore and is my go to place when I'm in the mood for it.
Fried carrot cakes: Comes in black (with dark soy sauce) or white. I don't really have a recommendation for this, basically just eat it if I see it in a food court or hawker center
Kaya Toast and Soft-boiled Eggs with local Kopi (coffee): A DEFINITE must eat that is not restricted to breakfast only. Ya Kun is all over Singapore, other choices instead Wang's and Toast Box. Kopi is cheaper than Starbucks and taste better too, IMO.
Crabs (Chilli or Pepper): As I'm not a fan of crabs.... No comment. But Singaporeans love them so you should probably try them.
Laska: 328 katong laksa is probably the one that you should try. Most of my laksa is home cooked and the only restaurant that I've eaten at for laksa is 328 katong laksa.
Curry Fish Head: My favorite is the Assam style due to the sourness, but again, most of my curry fish head is home cooked
Bak Chor Mee: One of my favorite food in the list, in fact, I just had it for lunch! My favorite is Meng's Kitchen at Upper Thomson Road but it can be quite out of the way for tourists.
Oyster Omelette (Orh Lua): I don't like oysters so I normally just eat the omelette part. I've only eaten it home cooked so I don't really have any recommendation here.
Satay: Good finger food, available in most hawker centers, you can't really go wrong with these.
BBQ Sambal Sting Ray: I LOVE THESE!! Can be hard to find these though and I can't think of a good place off the top of my head. Maybe others can chip in.
Tau Huay: I hate these but the rest of my family love it, as well as the soya bean milk drink. Mr Bean is a good place with multiple chains all over Singapore.
Chwee Kway: Another great breakfast food that can be eaten any time of the day. I don't really have a particular place to recommend as most places that serve it tastes great.
Durian: I hate this fruit but there's a result it's the unofficial fruit of Singapore.
Nasi Lemak: This is another great local dish to try. The rice and the sambal chilli is an addictive combination. My favorite is the Adam Road stall but I'm not sure if it's still there.
Roti Prata: An Indian dish that cannot be found in India, only in southeast Asia. Most places serve decent roti prata but my favorite is the one in Upper Thomson, Jalan Kayu, and casuarina prata. All 3 makes prata in a different style but you can't go wrong with any prata you find. My go-to supper food.
Chicken rice: My favorite place for chicken rice is Nam Kee at United Square. Nuff said.
Curry Puff: Singapore has lots of great curry puff. My personal favorite is the flaky A1 curry puffs
as a malaysian, i find these as common food available everywhere haha
