For old-school Hamburg class and outstanding seafood, you can choose no better than the Fischereihafen. Run by the same family since the 1980s, it combines formal elegance with warm hospitality and counts Prince and Princess of Wales among its more eminent guests. It may be plain from the brick façade but feels like the first-class dining room of a transatlantic liner as soon as you’ve stepped through the door, with candlelight, carpeted floors, white linen tablecloths and nautical scenes on the wall. Unchanged over the years, it’s by no means a hip joint, rather the kind of place you want to play a little vintage dapper and order a glass of champagne. The oysters, lobster soup, turbot and tiger prawns come particularly recommended, but everything here is first-class and supremely fresh. The views across the harbor are great by day or night, and service is impeccable. If it’s warm enough, book a table on the terrace.
