I am not talking about things that you can easily verify. I am talking about "flushing the radiator", "replacing parts that are not readily visible such as timing belt etc". Do you just trust the shop or is there a reliable way to verify the work?

hook a wireless camera up under the hood somewhere, they are still pretty expensive though and possibly your mechanic might argue that it was a breech of his privacy, saw this done once on TV by a news crew or somebody, it was in Texas and they caught several mechanics this way, some fast oil change places too, jiffylube I think, jiffylube stations explained that they were under a lot of pressure/ time constraints and didn't have the time to do everything they were being paid to do! maybe you could put some dye in the radiator or test your antifreeze before and after using one of those prestone antifreeze testers sold at wallmart

like everyone ells has seed ask to see all old part good shops you don't half to ask I always have the old parts in a box on the counter for the customer to look at when they pick up there car as for fluids like the radiator play stupid but interested ask where the drain petcock is for your radiator if it is dirty they did not do there job these are on the bottom of the radiator and are always dirty but when you open it your fingers clean it off

but most of all ask around a good shop will have a good rep always look for ASE certification for anything mechanical
