Like everywhere else, it depends on what you want to eat. I'm from Southeast Asia. So, to provide a point of reference, using Burgernomics, I'll begin with the price of a Big Mac in my country, which is $2.76.
From there, you can compare the rest of these lunch prices...
- Lunch at a roadside restaurant that serves really inexpensive local dishes. A complete meal with rice, meat, and a drink is $1.12
- Lunch at a casual restaurant that serves local dishes. A complete meal of rice, meat, some veggies, and a drink is $2.80.
- Big Mac Meal with a drink and small fries is $3.36. (But you can get the smaller Cheeseburger meal with the same fries and drink for $1.87)
- Lunch at a casual restaurant that serves non-local dishes. A main dish with a drink ranges from $5.60 to $9.33 (Depending on the cuisine).
- Lunch at an upscale restaurant. A meal with a starter and a main dish is $18.58. (You have to pay extra for your drinks).
- And if you're hungry and looking for an all you can eat buffet lunch, it will cost $13 to $30.
