You can try Biggest Hawker Centre (abt 260 stalls) at 2nd floor Chinatown Complex with a few stalls in Michelin guide. Another Hawker Center is Hong Lim Market & Food Centre which also have many tasty food. You can check internet on the recommended food at the specific hawker centre.
Singlish - Well explained by you! You can add some French into it, lol. We do the same here in Malaysia, hence we got this famous sentence "Wei macha, you want to makan here or tapau?". Singlish also has it own distinct accent, like how Aussie accents is different from American. Hawker Center - I think I'll rely on Google Maps recommendation, otherwise the previous few times I was in Singapore, I'll just eat chicken rice at the hawker center.
