You could easily pass by Lamason without noticing. I almost past by Lombard Street from Victoria Street. Lamason would be pretty incnospicuous from Lombard as well, except there is not much else on the street.

 Lamason is a small coffee lab run by two young bearded - AKA hipster - coffee guys.

 Toastie and carbonated juice was a small lunch but lasted me a full hour. The bread was toasted to perfection. Free wifi helped to keep me there, of course.
