They have several free tapas, the best for me is the garlic soup.
Typically leones
One of the highlights of my May/June 2016 camino. Fantastic atmosphere, packed with locals on a Saturday afternoon, moms, dads, kids, grandparents real slice of Spanish life. Best paella (as a tapa!!!) I ate in Spain. Love the server's outfits with the oversize flowers. A must to see the real Spain on your camino.
Escelentes tapas
Enjoyed a lot. Apparently frequented by the pijos in León but I didn't notice. Very busy but they seem to be able to handle large numbers. Good wine and I really enjoyed the sopa de ajo, especially on a cold December night.
Top tapas atmosphere
Imprescidible
Good place in Leon to have "tapas".
You get a free " salmorejo" with your drink.
They have a small area to sit down and eat "a la carte". You should make reservation.
