The closest I had to real ramen in Japan, taste wise. I had the tonkotsu ramen, ordered the gyoza and fried chicken (zangi). The gyoza was gone fast since I brought three guys with me lol. So did the fried chicken which was succulent and crispy. I've tried other places in Toronto but I'd have to say sansotei is the most authentic when it comes to their tonkotsu ramen.
There might be a wait however, just cuz it's newly opened and everyone and their mother seems to want to try it out. If you're uptown, definitely try to stop by.
