I travel to Argentina frequently on business and have tried most of the recommended restaurants for sushi: Yuki; Osaka; Japanese Gardens, Little Rose and always come away disappointed. However, there is a new glimmer of hope in an underground, closed door restaurant called Casa Mun. It seems that foreign born chefs are taking up the slack in the local food scene -- which I can only politely describe as boring. The night we went, there was a wonderful soba noodle soup, new style albacore sashimi with crispy onion, an assortment of maki sushi plus a delictable spicy tuna on crispy rice. And all without cream cheese. Anybody else been?? I later read on the website and that Chef Mun was trained by Iron Chefs Okuwa and Morimoto and it all fell into place....hands down the best sushi option available.
