Gourmet Experience is on the top (9th) floor of the El Corte Ingles Dept Store near Plaza Callao (there may be several in Madrid). There are about small 10 food counters (pizza, hamburgers, hot dogs, Mexican, sushi, sweets, sandwiches, salads,etc.), each offering reasonably priced, tasty food. Crowded with locals, which is obviously a good sign.
