According to yesterday's Chronicle:
"Charles Phan has finally named his Chinese restaurant and noodle bar opening next month in the Soma Grand (1160 Mission St.). It's Heaven's Dog, which is a result of a telephone game between Phan, bar manager Erik Adkins and chef de cuisine Andy Wai mixing up the names for a distilling process and a royal flush in a Chinese domino game."
It'll be interesting to see what's in Phan's ethnic Chinese roots and how Wai executes it. Not sure about that name, though, it's too easy a target for cheap jokes.
