So I've been doing this for the past few years, and by "this" I mean - trying to find the perfect place to eat at during Philadelphia's annual Restaurant Week. I use Yelp to track down the community ratings of each restaurant participating, and also note down the prices of each place. The "best" place to go during this week (or 2 weeks recently), is usually the highest ranked place that also costs the most amount of money (since it's a flat fee of $35 during the promotion).
So here's the list!
Looks like the best choice this year is "Chez Georges at Le Bec Fin", a French place underneath one of the most amazing restaurants in the city, "Le Bec Fin".
The spreadsheet is sorted by rating, but feel free to copy and paste the data down locally and mess with it to find your perfect place.
