Pro Large collections of candid customer photos
Lets you know what the dishes actually look like, not what it looks with an Instagram filter on.
Pro Search filters allow a lot of customization
"Most Reviewed" for popular restaurants, "Highest Ratings" for well-received restaurants, use the # of reviews the popular restaurants as an anchor for had to evaluate the restaurants with the highest ratings. For example, if popular restaurants have ~1000 reviews, then well-received restaurants with >4.5 stars and >200 reviews is pretty good. A restaurant with 5 stars an 20 reviews might not be as solid.
Pro Huge repository
It's hard to find any food-related business who doesn't have a page on Yelp. (If it doesn't, that's a bad sign)
Pro Review keywords are helpful for menu must-orders
If enough people have posted reviews repeating the same key words (e.g. tiramisu), Yelp will highlight them. A good sign of something you should definitely order if it's your first time at the restaurant, or something that the restaurant does particularly well.
Con Best Match is rarely the best match
The best match is usually the result of some continuous feedback loop of recommending the same set of restaurants to people over and over again, instead of the best restaurants in the area.
Con Android app lacks certain features
The iOS app allows you to use all the filters of the desktop site, but users can't sort by most reviewed or highest rating on Android devices.
Con Awkward photo presentation
They show from oldest to newest, even though the newest photos are more relevant. The desktop version of Yelp also has an old photo display system where you have to click to reveal each page of photos.
