It has almost six months since I last visited Puerto Madero, and it still has it's touch. With an excellent service, every dish is guaranteed to pleased you in every way: freshness, flavor, temperature and presentation. The place is always packed in rush hours (2-5 and 8 to 10) so if you plan to at these hours, it is better to have a reservation (but if you choose to wait, it is worth the time!).
Try the white fish: it is superb!
