I live just around the corner from this place and I'm sorry that I didn't try it sooner! It is very clean, and really reasonably priced as long as you stay away from the "specials" which seem generally higher in $$.
I have been searching for a good vermicelli with lemon grass and beef (#88) since moving here two years ago and they absolutely nailed it!
As for the service, they're very quiet, but efficient and attentive. I don't think the problem is that they have a bad attitude, but that they lack strong enough English to chat it up with the customers. Fair enough, they have you write down the numbers of your order and nothing gets lost in the translation.
Going back tonight!
