I have just come back from a trip to the US.
It was work and mainly in NJ but I got a free weekend in Manhattan out of it. The company I work for are awesome like that, if you are away for a weekend they will try to put you somewhere cool.
I had three burgers in the 2 weeks that I was there. Each time I was asked how I would like it cooked I had medium rare each time.
So before I went I tried to research the best burger in Manhattan and received tons of suggestions but this place looked a good bet: http://www.paulsburgers.com/
I knew as soon as I went in that I wasn't going to be disappointed, real 50's diner style layout with a counter, tables and a waitress that called me sugar.
I ordered the Eastsider, which is their specialty, along with sweet potato fries.
The picture from my phone doesn't do it justice. It was fantastic, it tasted like high quality beef and was really juicy. The bacon, mushroom and onions were also really tasty.
The bun was just some crappy generic white bread and I didn't eat it. Sweet potato fries were crispy and perfect.
Will deffo go back here next time I am in NYC. Almost worth the 30 hour journey.
Thanks for your burger updates - that looks delicious!
