Eating in Thailand is indeed very affordable.

1. Street stalls: Thailand's street food offers a wide variety of choices at very friendly prices. A serving of Thai fried noodles or fried rice and other common snacks usually costs only 20-40 Thai Baht, which is not only economical but also full of authentic flavors.

2. Regular restaurants: Dining in small diners or regular restaurants, a hearty meal costs about 200 Thai Baht, which is quite sufficient for two people.

3. High-end restaurants: Even in Bangkok's upscale restaurants, the average cost per person is only about 400 Thai Baht, allowing you to enjoy authentic Thai cuisine with great value for money.

4. According to local standards: If you live like a local, a daily budget of 30-50 Thai Baht for meals is sufficient, especially in smaller cities or rural areas where the cost of dining is even lower.
