Eating in Madrid

Wanted to give an update on a couple of restaurants and make a couple of suggestions
We had lunch at a couple of restaurants in the Rick Steves' Guide:
El Caldero - the food and service were top notch. The cod and cream cheese in puff pastry was not as expected (more like a flaky quesadilla) but was amazing as was the eggplant with grape molasses as starters. We did not have the "signature" caldron rice but really enjoyed the seafood rice (very much like paella). Fairly extensive wine list.
La Bola - They squeezed us in for the 1:30 seating (walk up) on Sunday. Good food, really active place. Professional but very busy waiters. The changeover from the 1:30 seating to the 3:30 seating (starts about 3:10) is fun to watch. It's a study in routine and efficiency with a bit of flair.
The Barcelo Market in the Chueca District near the Madrid History Museum (Metro Tribunal) is really outstanding. It's modern, seems to be high quality, and is not as crowded as the one near Plaza Mayor. It's more market than food counters and only open mornings until about 2:00.. The restaurant Bistro Barcelo is an amazing market-to- table restaurant with a Cordon Bleu trained owner/chef. It's small but they take reservations. Only open for breakfast and lunch (market hours).
