Kwanjai Thai is in a cute little "hut" on 35th Ave in Fremont. I don't live in Fremont and often forget about this little gem when considering my options for Thai food. Of Seattle's many Thai places, Kwanjai falls in my top 10.
The atmosphere is relaxed, cute and simple. It is not fancy but it is very clean with plastic checkered table clothes and sometimes a candle. It is a bit like a interior picnic, but that said it has an authentic "we're here for the food" vibe.
I have tried many of their dishes over the years and have not been disappointed. Their Phad Thai is good though not as "fried with egg" as Thai Toms in the U.Dist. Recently though, I order the Green Curry every time I go because it is done so well. Perfect coconut sauce, I usually get it with chicken and a decent amount of vegetables.
The prices are VERY reasonable, most dishes are around $6- $8 with all being less than $11. Decent size portions, some hungry guys can finish it, but I have lunch or a snack to take home after. The food quality is high, and there is no residual "I don't feel so good" for those with less-than-perfect-constitutions. With the Green Curry I find the left overs are as good (if not better, after marinating in the sauce longer) the next day, with no quality issues.
Service is quick and efficient. The staff is attentive to refilling waters. The food comes out fast and fresh.
Kwanjai Thai is great for a fast delicious informal Thai meal. Perfect for a single person grabbing a bite or a quick dinner before rushing off to a concert/theater/show. If I lived in Fremont, you'd probably see me there once a week. :)
