100 Maneiras is deservedly one of the top places in Lisbon. We were able to secure a table even though we had no reservation. The place is small and cozy, with an interesting creative menu (tasting menu 45EUR, plus 35EUR for wine pairing). Be ready for a culinary experience that lasts 2+ hrs. The staff is competent, with a great sommelier and friendly waiters. The best things I tasted were the codfish (tripes?) clothesline, the scallop sashimi with truffle oil, the smoked duck breast with wine jelly and topinambur puree. Everything was excellent (even the smallest details). The only thing I didn't "get" was the octopus with raw clams and basil "air": the ingredients were great but the design of the dish prevented my appreciation.
BOTTOM LINE: make a reservation and eat there. It's great for the the price and I ate better than at many 1 or 2-michelin stars restaurants.
