Hi, Boiworship,
One of the companies that I used, the gay owned one, is www.casasaltshaker.com. Twolovers, one an American and the other a porteno serve wonderful meals in their house on weekends. My good friend and I went and had the most enjoyable time. Most of the guests are tourists from various parts of the world. Take in this experience; I think you'd enjoy! The meal was quite, quite good, and the price less than one would expect!
