Perhaps, but then, "we typically have a couple of beers together at the end of the day" doesn't sound as novel or noteworthy as "we'll provide you with an unlimited amount of beer."

For better, or for worse, the "unlimited amount of beer" line is catchy. It's memorable. And it sends a very strong signal of the company's culture. That cultural signal will turn off quite a few would-be applicants, but it will attract many others. And isn't that the point of a well-thought-out job listing in the first place? You want to find people who'll kick ass at the job, but part of that ass-kicking is cultural fit. Perhaps a bigger part than many of us would admit at first blush. (In this particular case, they seem to be casting a line for New York hipsters. If that's what they want, great. If it's not, then they might want to rethink their listing).

Of course, there is certainly a way to take "startupy" culture too far. Recall the '90s tech scene, for instance. But that depends less on the culture in question, and more on whether or not the company is getting the results to back up the unique culture. A unique culture is pointless, and possibly even destructive, without productive results.
