FAQ Spice, Booking & Basics
Is "Thai Spicy" actually unbearable?
At places like Khua Kling Pak Sod, yes. If you are sensitive, ask for "Pet Noi" (little spicy), but be prepared for a kick regardless.
Do I need to book?
For dinner at Sri Trat or riverside Supanniga, absolutely book ahead. Thong Smith is walk-in only.
