I like Bangkok because:
1. Short flight duration of less than 3 hours
2. Plenty of food choices from expensive to economical
3. Many more skus in the supermarkets without hefty overpricing like in Singapore supermarkets
4. Great markets like Sampeng market and Chatujak market and unique malls like Mega Plaza.
5. If bored with Bangkok, can always book a car on Klook to go KhaoYai National Park for nature or take a domestic flight to Chiangmai.
6. Creativity is definitely much abundance than Singapore's rubbish when you go see their products whether it be snacks, clothes or other items.
Overall, its a great destination.
