Dunno about coconuts, but if you’re looking for tiki cocktails, Heritage Smokehouse of all places has amazing tiki cocktails. I believe Sugarvale does tiki cocktails too. Not sure if it’s an every night thing. Lucky Buns was kind of scratching that itch too for awhile, but they abruptly closed a little while back. Still hoping someone at some point takes the plunge and goes all in on a real deal tiki bar like Archipelago in DC or Hidden Harbor in Pittsburgh.
