There's nothing like a little local knowledge - someone who can point a visitor in the direction of the best pub or offer the inside word on where to find the least crowded beach spot and how to get a good price on tickets for the museum or gallery.
Chawadee Nualkhair's new book, Thailand's Best Street Food, is the little local friend you can carry in your shoulder bag when looking for the best deal on the streets of Bangkok.
Many visitors to the Thai capital want to try the legendary street stalls - in fact, you could feel like something of a failure if you returned from Thailand without at least one good recommendation on a cart selling fabulous pad thai or duck noodle soup (preferably with a selfie to add authenticity). This no-frills guide is the place to start.
In it, Nualkhair provides crisp directions (you'll find Jae Ouan Rad na Yod Pak on Yaowarat Rd "in front of a Rado Citizen watch shop, on the Plang Nam Rd side of the street"), tips on the best offerings from each stall (the pork noodle soup at Guay Jab Nam Khon Sam Kasat looks good) and key info on the facilities (the aforementioned place offers a "squat toilet, no flush, no paper").
Nualkhair, a Bangkok local, has produced a book of simple ingredients, with no florid garnish. There's a detailed map and the bare bones of each cart are laid out, from beverages to specialties. It's a recipe for success.
