I've been a regular at Langar for 6 years, and while it was a good DZ for many years, it's done nothing but improve in the last year or so.
It used to be a private joke that you felt you should thank the management for letting you jump there... now it is becoming far more customer focused.
The brand new shower/toilet block is 99% complete, as is the renovated bar area (all indoor areas are no-smoking at all times, not just during the day), and free WiFi internet access is also available.
The only real downside is the rather expensive/low-standard canteen.
