I have no idea if this is "authentic" or not but it is really delicious and everything is very nicely presented.
We've been a few times and had:
pad thai (the 4 year old's favorite),
tom yum soup (with tofu)
red and green curries
and some other stir fried noodle dish which I can't remember.
oh and we had sweet rice with mango for dessert.
Everything was really delicious. the curries didn't have that tell-tale canned taste to them. The larb was beautifully presented in a ring of green pepper with lovely cucumber "leaves" around the plate. It's a bit fancy for the neighborhood (considering you can buy crack a block away!) but definitly welcome.
The prices might be a touch higher than Thai Noon but totally worth it for me since it's less than 2 blocks from my house.
