I went to visit a friend in Madrid and during my trip ate here twice. We ate in the deli which I thought was great for lunch.
There is a LOT of choice which can be slightly overwhelming, and information about all ingredients in each dish. The deli bar contains soups, salads which you can get a selection of and pay by weight), sandwiches, pre-prepared plates (e.g. seitan and rice which they will heat up) and a large selection of cakes and other desserts (including vegan cakes). These things can be combined in a 2 course or 3 course meal, although the 3 course meal would be very heavy for lunch for one person! There is also an a la carte menu with more choice.
They also had good coffee and fresh juices.
I thought the food was good and tasted home cooked although not out of the ordinary - my friends had the vegetable stew/soup which was very comforting. I had an asian noodle dish which was filling, although not as full of flavours as I had hoped. I also had a vegan cake which was good.Pros: Lots of choice, Filling
Cons: Average food
