I've never heard of murger I must admit. It must be some take on a burger? And yes it seems to be - meat in a steamed bun Shaanxi style. This place near Euston station was a coincidence as the never ending queue at Roti King seems to always defy me.
£5 for a pork murger is a bit too much. The bread is firm and slightly charred - not bad as such. The pork meat is not particularly spiced either. It's ok overall but not worth that price. The photo that shows 3 of them got me thinking that would be a bargain for £5, but not to be. It's only for one.
On the other hand, the Biangbiang noodles (you get 2 per dish, but they aren't ordinary noodles) with braised pork, tomato, egg sauce, chilli oil also comes with a heap of grated ginger and a slightly tangy and salty broth. It's delicious. The noodles are thick and uneven like meat from a kebab. £10.8 isn't a bad price to pay for this.
I'd come back for the noodles.
