First challenge was finding the restaurant. Don't trust the Google listing or the address given on the Sushi Yama website as both will send you over 2 miles from where the restaurant actually is. The website lists the road as Estrada das Pereiras - but in fact the restaurant is right opposite Restaurant Aquarelle which is on Estrada das Escanxinas (just near Apolonia supermarket).
We went on a Thursday evening and it was pretty quiet. The service was not particularly friendly - we didn't warm to the staff at all and they made little effort to welcome us warmly. But the service wasn't bad - we were served quickly and we got everything we asked for.
The food was good, although the cuts of suchi on the €20 platter were particularly thin and disappointing. But the rolls was very tasty.
Overall, it is a decent Japanese restaurant but nothing out of the ordinary.
