Logo for Sushi Business

I would like the new logo to be along the lines of a piece of nigiri sushi (fish over rice) - but obviously would like it more refined and logo-like. The shape behind some of those is "lake tahoe" which might be able to be incorporated into the design.

I'd like something simple and eye-catching that will look good on the side of a truck, as well as on my website. We do very high end bookings so I would like it to portray luxury if possible.
