In the East Coast of the US where we live, most if not all Thai restaurants use "horapa" basil in their stir-fry dishes. "krapow" basil is rarely used and is quite difficult to find or buy. Glad that Thai restaurants in Thailand are able to keep their price down to help customers. Here, similar dishes to what you are showing ranges from $12 to $20 per dish. That's about 396 to 660 baht per dish. A good monthly salary (after tax) is about $6,000 per month. So imagine eating out at a Thailand restaurant and spending over $100 for each meal.... is very expensive.
