If anyone is traveling in northern California on 395 and goes through the city of Susanville, California (Lassen County)there is hope. A Thai restaurant called The White House. They have wonderful tofu green curry and other menu items they can make vegan. The fresh tofu spring roles and peanut sauce are excellent!
Beware! Many regular Thai restaurants have fish sauce hidden in pre-made sauces used in their dishes. Therefore, coconut milk based curry sauces, such as green, red, or massaman, usually are not 100% vegan or even vegetarian, because of the fish sauce added to them. You may order tofu and veggie red curry and think you're getting a vegan dish, but it's not. Since these sauces are pre-made, the cook can't take fish sauce out.
Your best bet is to get some kind of a veggie/tofu stir-fry and ask them not use fish sauce in the preparation of the dish.
