Went here tonight with two others for a late dinner.
What we sampled:
Fresh Rolls (very good)
Fried Tofu (even better, delicious)
Tom Kha Shrimp (good, not great)
Pad Thai Chicken (very good)
Red Curry Chicken (not good at all. the consistency was all wrong).
Overall the appetizers out-shined the main courses and I was particularly disappointed by the granular texture of the red curry. This is my litmus test for all Thai restaurants and this did not measure up.
In a neighborhood with great Thai Sukhothai needs to step it up.
