Solid 3. Good value for money.
I wasn't blown away by the quality of green curry and rice that I ordered, but for $8.80 or so tax in at dinner its pretty good. I'd probably go spicy next time as opposed to just medium, maybe it would be more to my taste, and try the soup as well. For a take-out lunch, I'd rather go get the $6.99 special at Sit-In Bangkok at College and Crawford.
As for the owner, holy cow, who beat the happy into him? I grabbed a seat last night as I ate my food happily watching this guy greet the customers.
