Not really sure as the resort we go to (Hedo) has a lobster night. I suggest asking the staff at the resort as they are usually very helpful. There is a lobster season when it is not available but not sure when that is.
My guess is that Lobster on the beach would be around $20 and a higher end restaurant upwards from there. Remember that they never have any change. <img src="http://www.traveltalkonline.com/forums/images/graemlins/jester.gif" alt="" />
