Brasserie Lipp has great seafood. I love their fish soup, their oysters, and all their fish dishes. Their non-food options also look to be good, although I never let myself order those meals, The wine list does a great job of giving you good pairings to the food. It's just the invoice that comes at the end which causes me to cringe a little. Perhaps the Swiss could arrange to lower their exchange rate for their currency so we can enjoy the aftermath a little better.
But if you can afford to eat I Switzerland, then I highly recommend this place.
