Gaucho is a very interesting place with a cool concept. A big line awaits you when you walk in and it is not the people who are waiting to be seated but they are also placing their orders. You can order your meal and beverages at the check in counter and pay for it too. The waitress will get you and find a seat. Then someone will bring in your food and serve it at your table.
Now I liked most of my experience but when you are looking for any service at your table, you would barely get any. Probably because I was there between 8 and 9, I don't know. The food was very good, I ordered small plate of camarones (shrimp), veggie empanadas and chicken sandwich. Their sauces are a must try!
If not for their poor service at the table and the wait at the front, it is a 5 Star experience!
