The service at Caseros was exceptional. We speak limited Spanish and couldn't understand what something on the menu was so our waitress mimed "lamb" for us. She did a great impression of "shrimp" just to humour us. My wife and I shared the risotto with roast mushrooms and it was fantastic. I had ravioli with shrimp and my wife had the salmon on greens. Both were excellent.
You should understand that we're from the salmon capital of Canada, Vancouver, so it takes a great deal to impress us. This was impressive. I would highly recommend making the journey to Caseros.
