As far as Asian restaurants with authentic tastes, you're not going to find any, believe me, I've tried to look for one that is. I was trying out the restaurants in "Barrio Chino," BA's equivalent Chinatown here. I usually go to Asian restaurants where most of the clients are Asian because these are the places where food is authentic, and Asians tend to shy away from the "Americanized" places where the taste is altered with substitute ingredients. I've also had Thai food here in Retiro, AFAIK, it's one of the ONLY 2 that exists in Buenos Aires. It's as bad as trying to find a pizzaria that offers NY style pepperoni pizzas (if you know of any, please let me know because I'm STILL looking for one.) The quality is so-so to horrible at best. The taste is nowhere close to the Chinatown in San Francisco, Los Angeles, or New York, where the Asian food is excellent. The lack of the ingredients is one of the main factors. When I was living in Hollywood before I moved here last Jan. I've always had to drive 7 miles across town to Chinatown in downtown, or even further (12 to 18 miles) to the east side of town, like Monterey Park, Alhambra, or San Gabriel for Asian foods.
