Arce is one of my favorite restaurant in Madrid. My most recent meal last October was excellent. Chef recommended tasting menu: saute foie gras, salmon tartare, seafood croquetas, roasted cigales, beef with wild mushrooms and assorted items from the pastry table. Allow plenty of time for a leisurely dinner. I've written many posts on Arce on this board.
I have not eaten at either Zaranda and Montana but would appreciated a post if you dine there,
I ate at Arce last Friday (Feb. 15). I went to La Broche for lunch, then had dinner at Arce. I thought Arce was excellent, not just because of the food, but also because of the very cozy atmosphere and the individualized attention from the chef (he sits down with you before the meal and discusses your preferences, then tailors the menu to them). Although I'm blanking on all the dishes we had, some of my appetizers were: truffle slices on a bed of jamon and crepe; and egg yolk in a fried potato cup (think more like potato chip). My entree was a sole with a green mustard sauce and some fried chives (I think). Everything was delicious, and we thought about going back for dinner on Saturday, but wanted to try something else as time in Madrid was limited.
