I have only been here a couple of times for lunch and haven't tried much on their menu but my experiences so far have been ok. Nothing was bad but nothing was really memorable either.
It's a little place that feels like a converted wendy's or other fast food restaurant without much character. On both occasions, we stuck to the 'lunch specials' but i think i'd be happier ordering from the regular menu. SaBai serves standard traditional Thai/Fusion fare with typical offerings of stir-fry, curries, and the like.
