Martin's been fixing my bikes for years. Whenever I go somewhere else for a tune-up (i.e. cheat on him), I end up regretting it and hafta go back to Martin.
I commute about 30 km a day, 10 months of the year. My bike takes a lot of abuse, but Martin always gets it into top shape. He's really knowledgeable and cares that you're going to enjoy your ride. That's what motivates him, not the sale.
Lovely store, lovely guy, lovely bike rides!
(Keep your eyes peeled for the new store - if you're not careful, you'll miss the discreet signage and have to double back)
