You're seated outdoors at a wooden picnic table overlooking the Miami River, with a little dish of dolphin dip and a green plastic basket of Saltines in front of you. Nice start. An ice-cold draft beer ($2) arrives next, set down in a frosty glass by an amiable waiter, followed by a hunk of grilled dolphin -- freshly filleted up front in the fish market -- delivered in a fluffy bun ($7.95). Sandwiches come with choice of fried plantains, French fries, or any of a number of potential sides. The river rolls by. Time flows on. Life is composed of many sweet moments, and this one costs less than $10 -- assuming you can resist a second beer.
