We went last weekend and no change to get a table without reservation, the place is comfortable as well as the lounge with lagoon view. They also have tables outside but we decide to stay inside in the air conditon. Not so many options at Puerto Madero but the same food style, meat was great and service need to be improve. This restaurant if from the Anderson chain (Carlos & Carles, Sr. Frogs, Shrimp Bucket) but more fancy and expensive.
