> “Do I want to spend $20 and risk the food being awful, or do I want to go with the safe option, the place I’ve been to a hundred times?” This problem didn’t really exist prior to review sites
Actually, it very much did.
The answer is that you suck it up and go to the new place--live a little.
I eat at a lot of different places. Normally the food isn't awful--most are just mediocre and I won't be back without some other reason (There is an Asian chain restaurant in London that was so BAD I can't even remember its name--that's one of the exceptions). Some are good, but too expensive for what you got--they go on my "If someone really wants <Food X>, I can take them there."
And then there are the few that are "good and reasonably priced (or maybe even cheap)". And the occasional "Expensive, but worth it".
Those are the ones you will recommend when your friends ask.
