I've been into this shop several times. I even dropped $300 in one go when I had two bikes tuned up and parts replaced at the same time.
The service is very mixed. One day you'll get a nice attentive staff person and the next they can barely be bothered to speak to you. One time I got a rather p1ssy lecture off a staff person when I asked a simple question about replacing handlebars. I guess my question was too dumb for him.
Anyway, the final straw for me was that after spending good money on a thorough tune-up for one of my bikes, I later discovered that both the tires had serious dry rot. This caused a significant problem for me later on. I didn't know tires could get dry rot and wouldn't have known what to look for, but for what I paid for the tune-up, shouldn't the bike mechanic have noticed? Especially since in all likelihood I would have bought the replacement tires from him - more $$ for the shop. But no.
Oh and one other thing, I mentioned to one staff person that I had just bought a third bike (Dutch step-through) and he made some negative comments about that style of bike (heavy, can't go fast, not great on hills) and it just struck me as unnecessarily crabby. The Bike Clinic doesn't sell bikes so it's not like they lost a sale to a competitor. And, this is the part that got me, wouldn't a freaking BIKE MECHANIC know that different styles of bikes are useful for different purposes? There is no point in bagging on one type of bike, because whatever it is it's doing the job someone needs it to do.
Who needs the negativity? There are plenty of bike-repair places in this area.
