We visited the Penang and Tokyo Restaurant on Water Street Friday afternoon.
It has three menu sections: Pretty typical Chinese American, Japanese, Malay. We had vegetarian sushi combo for about $12, a side of Spinach with fresh garlic $9, and white rice. This was too much for two of us to finish even though we were hungry. Quality was quite good although the ginger for the sushi was a bit tired and the sushi itself was cut very unevenly (but tasted great).
The menu talks about the food of Chinese people in Malaysia and I asked the owner(?) on the way out if they were referring to Nyonya cuisine. He said that that was food of Chinese who intermarried and the food there was of Chinese who simply had migrated there.
Anyway, was interesting and worth another visit to look at the Malaysian food section (which included Tom Yum soups, a Thai specialty).
