Plenty of places in Chiang Rai with Western food, although I or my GF cook for ourselves most of the time.
Eating out, Cumberland sausage and mash with peas, Spinach and cheese omelette, whole roast fish, Caesar salad.
I also like Thai mussuman curry, pad thai goong, and pad siew gai.
Then there's a ham, cheese and salad roll with a mango smoothie. 180 baht at the Hungry Nest, Jetyod Road, Chiang Rai
