Inspectors for the Guide Michelin eat around 250 meals in restaurants per annum, all with wine, ranging in price from around 50€ for lunch in a 1-star to 500€ for dinner in a 3-star.
If you're ever in danger of thinking this sounds like a glamorous lifestyle, bear in mind that they don't get to choose where to eat and not every restaurant they visit is good enough to get in the red book... in fact, the hit rate is quite low. They also tend to travel and dine alone - although the guide pays for the inspector's meal, they don't pay for companions to eat as well.
Never worked for Michelin but I have worked for other restaurant guides and did quite a few inspections in my time. It sucks all the fun out of eating out. At least Michelin inspectors are professionals. The ones I worked for employed inspectors on an amateur basis - ie they didn't pay for your time, only for your dinner (although one of them did at least stretch the budget to cover a companion's meal as well).
Never got to visit any three-star places* but did a few that were two-star level. Also got to visit some places that were truly terrible.
(*I did once have dinner at Sketch in London, but that was long before it got its third star and frankly I didn't think the food came anywhere close to justifying the £450 bill for dinner for two - which sounds a lot even now, but bear in mind this was ~20 years ago.)
