Asador el Gaucho, San Antonio Bay - Argentine steakhouse unaffiliated with the Gaucho chain.
Great service and still warm enough now to eat outside on the terrace post sunset - we ate here last in May 2018 and had to eat inside.
We opted to share 850g of the T-Bone - allegedly special in that the cows are feed chocolate in their final month and get to listen to classical music... bullshit aside, it was delicious. At €92 total, which included a btl of Malbec (€19), bread, alioli and olives to start, table water plus sides (chips and stuffed peppers) I thought it was very reasonably priced, even if the food didn't blow us away. It was still well above average. Would go again and probably opt for the fillet instead of the gimmick.
Only negative I can say is that there were two separate instances where boozed-up Brits walked past deliberately making a spectacle of themselves. Absolute show ups
