I've passed by here dozens of times never lining up because of wait time. Finally, I passed by on a day where the line was only about 20-25mins.
I was a little weary of the cheesecake since I've heard polarizing reviews. However, I thought it was good, light and not too sweet. It definitely doesn't taste like a traditional cheesecake. It's texture reminded me of ricotta cheese.
If i had to say whether it is worth the wait? No. But it definitely is worth a try.
Side note: The madeleines were very tasty. You don't have to wait in the long line for those!
