So basically every bar in the city won?
Not quite. We list about 640 bars in our directory. There's lots we don't bother to list, so conservatively speaking, I'd say there's 1,000 bars in Beijing, as least.
Therefore:
23 bars (or 2.3% of the city's bars) won a "Best" award in any given caregory.
Another 5.7% won some sort of "Outstanding" award.
So to answer your question, 2.3% + 5.7% = 8% of the bars in the city (or 1 of every 12.5) won an award of some kind.
