I would contact the restaurant directly for reimbursement of medical costs. The way I see it, they should cover the real costs you incurred, not make you independently wealthy.

Chances are, the restaurant is either independent or a franchise. Suing would probably force them to close their doors, and probably wouldn't win you much money....much less after the lawyers extract their fee (30% - 50%).
