Narcoossee isn't known for overly-large portions. I think the price reflects the upscale nature of the restaurant, rather than the size of the lobster. Those are some beautiful lobsters though.
That looks like a decent sized lobster. Last time I was there I had the filet and lobster tail. I enjoyed the tail better than the filet. Overall I enjoyed the restaurant enough to want to go back. The cheesecake with cherry sauce was to die for!
I have had the lobster 2x but it has been about a year or so. As I recall, I could not finish my plate. Good thing my husband was with me "help" me out.
