I would add Sint Maarten Yacht Club to the list of places to casually dine. It's by the Simpson Bay bridge so an outdoor table will not only give them views of the marina but yield very good yacht watching while the boats enter and exit during the bridge openings.

They serve some of the best Bloody Mary's we've every had which we enjoy with breakfast. Eggs Benedict are wonderful as is the grouper fingers (lunch or dinner. They serve breakfast, lunch and dinner.
