My wife and I are going to be in BA for a week from Oct 15. We are staying in the Elavage Hotel on Maipu near the Plaza San Martin. As we are flying all night from Canada to get there, we will not want a big meal the first night in BA. Are there any Tapas Bars in this neighborhood or the equivalant type of bistro or bar where one can get a bottle of wine and a few smaller portion dishes to snack on? What is the alternative in Argentina (first trip) to the Parillas and full service restaurants when one needs good food but not a huge meal.
