I did it so you don't have to! I was working at Canary Wharf this morning, so I thought I would pop into UDAC as it was only three stops away.
The lesson is, don't bother, until you received the email saying its ready. I know they've already said this, but I was gambling that it may be in the system as there's only 7 days until lockdown.
Opening times are early until late, 7 days a week. The nice lady said the best time to go is between 5 and 7 as there are no queues then.
Off to Tap East in a while ready for tonight's rehearsal.
