Erno's Bistro
This tiny, unpretentious place in a quiet Westend neighborhood seems an unlikely candidate for the best restaurant in Germany, yet that's how top international reviewers describe it. Fresh seafood, the specialty, is often flown in from France, as are the wines (the wine list boasts 600 choices). It's closed weekends, during the Christmas and Easter seasons, and during much of summer—in other words, when its patrons, well-heeled business executives, are not likely to be in town. Reservations essential.
