If you happen to stay at the Marriott Hotel by AC Carlton Madrid, this should be your go to breakfast place. First of all, you should never eat at the hotel unless it comes with the room. The breakfast at hotel will be overcharged and never authentic locally. Dominguez solves this problem in 2 big ways: one it is about a 5 minute walk from the hotel giving you time and chance to come back to room to freshen up before you move on your day, and two it has one of the best authentic Spanish breakfast in town. We tried the vegetarian sandwich and ham/egg sandwich our first day, accompanied by 2 fresh Spanish coffee. Honestly, we were taken aback by the quality and deliciousness of the meal that we went on to order one more churro and croissant, which were excellent as well. Don't look back and try this place; the convenience factor and delicious meal more than warrant this. read more
