Mussels?

I have a friend coming for dinner tonight and I am having trouble deciding what to cook.  I will walk over to Kensington to do my shopping.  The thing is with this particular friend, I feel as if I can take bigger risks with what I cook.  I have never had mussels before and am thinking tonight might be the night.  How ever I have also been thinking about scallops and filet mignon. I will go shopping and decide.  I only started eating sea food in December of last year...stay tuned for the adventures in my kitchen
