"Gilmore Girls" turned 16 on Wednesday (October 5), and Netflix celebrated in true Stars Hollow-style — by transforming 250 coffee shops and cafes across the country into Luke's Diner for a day. And oh my Gilmore, was it awesome.

In the spirit of investigative journalism, I took on the burden of visiting one of the New York City pop-ups, The Bean in Union Square, to see what was a-brewin', and to answer one of our most burning "Gilmore Girls" questions — is the coffee at Luke's as good as Lorelai says it is?

At New York City's Union Square Luke's Diner pop-up, "Gilmore Girls" fans began lining up outside at 5:30 a.m.

The first 250 customers were promised free 12-ounce cups of coffee. That ran out by 8:55 a.m., but of course, that's not really what people were standing in line for anyway.

Inside, show-specific details abounded — like the Luke's Diner coffee sleeves on every cup.

The cups also featured coffee-themed quotes from the Gilmore ladies, like Lorelai's classic one-liner: "I need coffee in an IV."

The staff also sported Luke's trusty flannel-and-baseball-cap uniform.

Only, they were a lot friendlier than Stars Hollow's grumpiest diner owner!

Look at this guy! He's basically Luke Danes II.

NAILED IT, dude.

After some painstaking research, I'd venture to say the coffee was actually *better* than what Luke serves up.

No offense to Luke (or Lorelai), but his coffee was definitely pre-ground and came from a suspiciously generic-looking tin. The freshly ground coffee at The Bean is definitely better.

Luke might not approve of my opinion of his coffee, but he'd definitely agree with the pop-up's rules for the day, as seen on the cutout behind me. They were as follows: No texting while ordering; no man buns; no taking pictures of food; no headphones (if I can hear your music through your headphones, why are you wearing headphones?). Touché.

Plus, they even remembered Luke's "No Cell Phones" sign!

Not that any of the selfie-snapping customers paid it any mind, but it was still a nice touch.

In between gulps of coffee, the crowd was quizzed with "Gilmore Girls" trivia.

And there wasn't a question too obscure for these folks. At one point, the shop's manager, Kira Rudgen, asked the crowd how many episodes Kirk Gleason appeared in under a different name, and one woman immediately (and correctly) yelled out, "Two!"

"People’s eyes light up when I ask a question that nobody really knows," Rudgen told me afterward. "It’s such a community feel that we have going here."

How very Stars Hollow, indeed!

To round out the day's festivities, Netflix also released a special "Gilmore Girls" featurette.

And we're feeling more nostalgic about this show — and more hyped up on caffeine — than ever.
