I recently made my first trip to South America and have to say that Buenos Aires, Argentina was really fantastic. While we were there my husband and I ate at a puerta cerrada which is a closed door restaurant that takes place in the house of the chef. You're offered a fixed menu that includes four courses including wine pairings for only $40 per person! The local and friendly sommelier greeted us at the door with glasses of champagne and welcomed us into him and the chef's home. Food was OUTSTANDING and the sommelier was not shy with re-filling our glasses. It was hands down one of the coolest experiences of our trip. It's intimate but not pretentious in any way. And it's only 40 dollars!! I highly recommend this to fellow travelers if you want to dine like the locals! Oh yea, it's reservation only and called NOLA Buenos Aires!
