A friend an organised a celebration event at Arena. I am not sure how you would describe this place. A mix of a Bar, Restaurant and Nightclub venue rolled into one. The food was Indian and prepared to a good standard. Overall we had a good time. The entrance is a couple of doors away from the Hendon Central London underground tube. It is a tiny single doorway entrance, so easy to miss. The entrance leads to stairs below into a basement. Towards the end of the evening, they opened the greyed out windows and it was possible to see Underground trains going past! A bit of novelty! I checked their food hygiene rating and it was 5/5. However, the starter plates, looked like they had been hand washed. I prefer plates which are dish washed. The main dish plates were spotless.
