Deck 84’s blackened mahi fish sandwich stacks a spice-rubbed fillet onto a sandwich roll, typically with slaw or fresh toppings and a side like fries. The waterfront setting and emphasis on blackened preparation give this sandwich a more coastal, Floridian character than many generic fish sandwiches. You get a pronounced crust on the fish that contrasts against a moist interior and cool toppings, with the bread soaking up spice and juices without falling apart. Photos and descriptions from multiple sources point to this as one of the go-to handhelds for people wanting mahi while sitting by the Intracoastal.
