Tartarun
$$$
While most of the restaurants lining Marsaxlokk's waterfront are rather cheap and cheerful, aimed more at the ravenous lunchtime crowd, Tartarun not only skews more upscale but also makes superb use of the island's seafood—it is literally fresh off the boat. The atmosphere buzzes with intent, and light pours through its huge windows. There's no terrace, but you'll get more than a taste of the sea from the menu, with the prawn carpaccio a classic opener, followed by roasted sea bass and clam sauce and fried lentil or perhaps one of the fine local lobsters.
