What is the best authentic tapas bar in Madrid?

Question

I am studying in Madrid and want the authentic flavors, not the tourist traps. Where should I go?

Answer 1

Los Chili's, de Beniganos, or Lobster Rojos, I would think.

Answer 2

la trucha.

Answer 3

go to any side street tavern looking place.  i remember getting lost in madrid one day and stumbling on this place.  i stopped in to get a quick beer and wound up getting a ton of food basically shoved in my face.  i kept trying to refuse things, but they wouldnt hear of it.  look for small places with old people hanging around.  it seemed like the places that had mahou signs were good.  ask the locals too.

do you study through SLU?
