If you need a quick tune-up, this is the place to go. They have knowledgeable mechanics and can get your bike back to you quickly.
In terms of parts, the shop is pretty small and you might want to call them and checking before going for a part. Standard stuff is all there, though.
Also---if you like Bianchi, this is the store for you. They have more new Bianchi brand bicycles than I have seen in any other bicycle store.
