This delicious dish plays to the many strengths of perfectly fresh local lobster.
Lobster Cardinale is very tricky; you will do well to think it through carefully before committing to it for company. A lot of the work must happen at the very last moment, so it could be a disaster to attempt for more than four diners. To be honest, I would want more experience before attempting it for four.
That raises another issue: can be a pricey dish to practice with. The lobsters really must be Selects or bigger, and there's the black truffle to deal with. This is a dish best suited to practicing with unabashed and unjudgmental foodie friends!
