Spaghetti House has a rustic dining area but feels a bit dated. There is seating on the lower level as well as a few outdoor seats. The upstairs restaurant is not very spacious and feels a bit cramped. The menu is colourful and quite a few of the items look enticing. The staff are quick to take orders and also to bring the bill at the end of the meal.
Finding pure vegetarian food in Madrid can be a slight challenge. Then like buses, two come at once. One was a vegetarian/vegan buffet place and then just opposite was Yerbabuena.
