I don't get the negative reviews here. People in Toronto are stupid - the hype surrounding David Chang isn't because he makes great ramen; it's because his higher-end cooking (Daisho and Shoto here) is fantastic and fun.
Ramen is okay; chilled spicy noodles are the way to go, though. Pork buns are fantastic and just like those in NYC. (Newsflash to health-conscious Torontonians: The fattiness is what makes them great.) Service is friendly and efficient.
4 stars just to outweigh the negative reviews here of people who seemed to expect that a bowl of ramen would be more than just that.
