Islamorada Keys Guide has a Map by Mile Marker of Restaurants with quite the variety of best food - expensive & budget - with dockage around the water.

Find your way by Mile Marker (MM = street address) to live entertainment, best Islamorada tiki bars, great views, bikinis & sandals.... It's always fun to wine and dine at restaurants with the local boaters!

Hence, if you were telling someone where to meet you, you would say Mile Marker 81.8 Bay Side because it's on the Florida Bay side of the road.

So looking at the restaurant map of Islamorada above, if you are going to a place on the "ocean" side of the key, you would say the same thing ocean side.  Knowing bay side or ocean side makes you aware to look to the left or right while driving.  This Mile Marker translates to 81.8 miles further south and you will arrive Key West at Mile Marker Zero.  Easy!

The area hosts a multitude of casual and high end restaurants.  Popular boating destinations are shown below - amongst many others via car.
