Hellmann's Burguer-lovers Route

From past June 2nd to July 6th, Hellmann's is sponsoring a new idea in Madrid and Barcelona: a route of 20 restaurants in each city, that have created a new burger specialty that includes some Hellmann's sauce in the recipe. There are very original creations, from one that includes grilled peach, to other made of bison meat.
Users are invited to vote the best of them in the web, and a motorcycle will be raffled among the participants.
The restaurants in Madrid are scattered in the following districts: Centro, Retiro, Salamanca, Arganzuela, Chamberí, Moncloa-Aravaca and Chamartín.
There are traditional restaurants as the well known Alfredo's and the "Pecado Carnal" ("Carnal Sin"), and some newer ones, as The Mad Cafe.   Here's the list of all 20 participating restaurants in Madrid:

Antigua Casa Narcisa (Former Narcisa House)

In a tweet: Amazing cozy terrace, that invites to have a long and pleasent table talk. Ambience is the most remarkable quality; some dishes are good; above average, but not reaching the A.

In a tweet: Posh, modern and fashioned "cocktails and food gastrobar", where you can ask for "gastrotapas" (60% of the whole dish), so to try more dishes. A bit better than average, but not exceptional. A wannabe...
