They are both outlets at food courts of this restaurant called Lotus Thai Restaurant. What I do recommend here is their good value for money pineapple rice (only S$4 for a portion) & their mango salad (S$3.50).
You can also opt for their pineapple set (for S$6) which comes with the normal portion of the pineapple fried rice, a small dish of mango salad and a bowl of tom yam soup. I find the tom yam soup (clear one) not that spicy. They do place a bowl of their chilli padi, normal cut red chillies and chilli powder outside their stalls so you can help yourself.
I’m disappointed by their olive rice though. It doesn’t really give a tasty flavor, so I would avoid it if I were you.
If you have the kopitiam card, you get 10% discount. Add $0.20 for take-aways.
