Couple of Sushi Questions - NCL Dawn

[cruisin'sz]

Is Sushi available for lunch or just dinner?

 

Also, can you go to the Asian restaurant with a group of people and have some order Sushi, some order Asian food and some order Teppanyaki (sp?) instead?

 

Is it or is it not all you can eat for $12.50?

 

Finally, how is the Sushi on board the Dawn?

 

Thanks.
