Popped in here after work today to ask about a service. The gentleman who served me was friendly and hugely helpful - instead of doing necessary work, he advised me that my bike was good to ride for a while longer and sent me on my way with a complementary oiled chain and adjusted brakes. I would have loved to bring my bike back for a service in a month or two, however it was stolen from outside a different shop only minutes afterwards. That's London for you.
