It's a chain, famous with locals here. And a good (AND CHEAP) first experience for tapa crawlers. Very Spanish: a plateful of tapas come free with your order of rioja, sidra or cerveza. A bit "messy" but good enough to eat standing. Yes, standing!
Rioja in a glass. Jamon con pan, a couple of chicken wings which they call "alitas de pollo", some pimientos, patatas, carrots & green beans thrown in. At 3.50€ for the whole deal, who's complaining?
Like many tapa bars in town, don't be shy littering the floor with your used napkins. In fact, a good bar boasts of littered floors where unpopular bars have none. And don't mind sticky floors either! 😄
An El Tigre branch can be found just off the corner of Gran Via and Calle Hortaleza. Madrid. Here's a map (don't mind the marker, please) -- check out Gran Via and Calle Hortaleza.
