A burger and shake joint in the city that has an average of a two hour wait to get in … is it worth it?

When Madeline started talking about how she wanted to celebrate her birthday some six months ago, she was very clear about her ideas.
She wanted to go into the city with her two best friends and spend the day. She asked if we could, and I agreed, and then we didn’t discuss it much after that.
We planned a low key party at home to celebrate with her friends, and I think she figured I had just decided against taking her into the city.
Which is exactly what I wanted her to think.
Because it was far MORE fun to surprise her.
I had made arrangements with her friends’ mom, decided on the day, and didn’t tell Madeline until we were on her way.
A boring Saturday of just “doing some errands” turned into a giant surprise for her, and she couldn’t have been more happy.
When I was planning what we would do, I wanted to stay away from the general area of Times Square.
Although it is heaps of fun, and there would be plenty to do there, I was going to be the only adult with four kids, and I don’t trust my NYC geography nor crowds quite that much. So I kept my focus on the Meatpacking district and built our day trip around lunch at Black Tap. 
If you’re on Instagram or follow Buzz Feed, and, well, countless other social media channels, you have likely heard of Black Tap before.
Or perhaps seen their crazy, over-the-top milkshakes.
Which I thought the kids would be thrilled with.
They have two locations (the other in Soho), but I went with this one because I figured we could also visit the Chelsea Marketplace, the High Line, and the four-story Apple store (for Nick) while we were there.
Keeping everything in the same general area, and easy walking distance.
I also thought this location of Black Tap might be the least busy of the two.
Well…
Since they have generated quite the buzz on the internet over the last few months, it wasn’t exactly empty.
They open at 12, and we arrived around 11:45, and the lines were already three rows deep.
It took just under two hours to get in.
Craziness.

Luckily the weather was gorgeous, and the kids kept themselves busy most of the time. They only started getting antsy towards the last half hour, but luckily we saw the light at the end of the tunnel.
When we were next in line to enter, I asked the guy manning the door about the crowd. He said that was his first day working there and he was a little astounded. I’m not surprised. (*Just a side note, after we had our meal, we did the rest of our sightseeing and had to pass by the restaurant around dinner time. By then, the lines had doubled, so those folks had a good 3-4 hour wait to get in.)
Once inside, the restaurant is actually quite small. A long bar on the right with bar stools, a few community tables, a bunch of booths, and a back room. (The Soho location is actually smaller, seating just 18 people and many reviewers warn against going if you’re claustrophobic because of the tight quarters).

The tables are wooden and patrons have been doing their own form of decorating on them (bring a marker!). Each table is set with condiments, and a serving tray with silverware and menus.
Very no frills.
Our waiter came by with a jug of water and jelly glasses.
As Nick said, “mmmm, New York City tap water.”
You start by ordering your shakes first, and then your meal, and that’s how everything comes out. They are three of their “fancy” shakes on the menu, and when we got there, the cotton candy version was already sold out (even though they had only been open for an hour).
