On our last night in Ponta Delgada (earler this week) we visited the Bonsai to celebrate our wedding anniversary. The food was exceptional, and the staff were superbly efficient in delivering a very good dining experience.The restaurante was recommended to us by our concierge at the Marina Atlantico Hotel. It is also called 'A Grelha' (The Grille) and is reflected in the menu. My wife and I tried the beef which is local to the islands. It was perfectly grilled, tasty and delicious.
I would thoroughly recommend a visit to this restaurant.
