This place is not bad. I've been here 2-3 times over the years. I've had pad thai and some curries here. The curries are good. For pad thai, it might just be a personal preference but I like Salad Kind's more. I'm also pretty convinec that SK's portions are slightly larger.
It bothers me a little when a place is not authentic. I'm open to the idea that the staff don't need to be Thai to serve authentic Thai food, but when you also serve sushi in a Thai restaurant, I start to question the authenticity. The decor is also more run-down compared to Salad King. This is very typical of Asian owners who focus more on being practical.
The prices don't really induce me to come here over Salad King. Salad King is about 5 mins walk away. Salad King also has a stamp card system and free spring roll coupons can be obtained easily from my friend. There isn't enough reason for me to come back to Evergreen. The only exception is if I really want Thai food and really need a sit-in restaurant and Salad King is full.
