People tend to check in during these times:
If you need to use the toilets, use level 1 toilets beside the conference rooms. They are much cleaner and maintained than all the other levels.
The cafe in the lobby does a decent toastie and it's cheaper with a coffee.
Across the road is PJ's and you have to try their bacon & egg breakfast roll. 4 slices of quality bacon and runny egg on a fresh roll. Becoming a habit.
