We've eaten here a number of times over the years and always found it to be amazing. I was dragged here by my fiancée a few years ago along with my deep suspicion of all foods fishy, and refused to eat any sushi - right up until her food arrived and I nibbled a corner... Since then we come back at every opportunity!
The sashimi is divine and having worked through most of the menu now, we have yet to find anything we don't like. In addition the service is second to none - they effortlessly manage to remember what we ate/drank on the last visit, and any odd requests from my fussy wife!
Oddly, because its just off the Main Street (literally 50 feet) it seems to get overlooked, and taxi drivers struggle to find it. Just get to mediocre Mykonos (not worth eating at), walk past with Mykonos on your left and take the next little street on your left, Maya Sayang is just up here on the left.
