This is my second time eating at Rincon on a Vegas visit. I'm of Argentine heritage and can confirm that this is authentic argentine food. Parrillada is a must to get the argentine experience. It says on the menu that it feeds 2, but that must be for people with huge appetites. We got sides of Spanish rice, ensalada russa, and ensalada mixto. With the sides we fed 4 adults. They also give you bread and chimichurri for $1.75. We got dessert of alfajores and Mil ojas to go. Both delicious and the alfajores were exactly like you get in Argentina. Prices are OK. The sides are actually the only thing I thought were over priced and the only reason I did not give 5 stars.
