Greg McMenaman has come up with a concept to spur any flagging appetites at Blacktip Reef: a pet shark that trolls its wall-sized tank immediately adjacent to tables where you're chowing down your Delray fish taco or Bermuda conch chowder. There's something about that vision of pure, insatiable hunger that makes you want to keep ordering conch fritters and raw oysters, and keeps you longing for pan-seared grouper with a little mango risotto on the side. Blacktip Reef is as much neighborhood bar as it is gourmet fish house — the crowd ordering baskets of steamers at the bar, or showing up for "shark hour" drink specials, is drawn from a cross-section of Delray. Here's where the minnow swims happily with the barracuda, the lobster with the hammerhead: lawyers, deep sea fishing guides, secretaries, the temporarily unemployed, bricklayers, PR ladies, and yachtsmen glide fin to fin in Blacktip's Caribbean-hued light, only baring their teeth for another bite of blackened wahoo.
