Must be a grand place that can serve something like that 
Not really;) You can buy it in the store (when its season for it), and prepare it yourself.
Got seal served once (long time ago) when I was visiting my aunt.
Its not as common now, after the huge protest against sealhunting. Same goes for whale.
The meat is dark red, almost black, and got a quite ....donno how to describe it.. Raw taste.
Special, but good.
