TL;DR - charges up front, buggy app, not a lot of choices, use open table or Yelp.
Im not sure what sets this app apart from the other big names in reservation services, except the part where they charge you in full the moment you make the reservation. While it may seem convenient, I would prefer to be charge the day of the meal rather than completely up front. The app itself was extremely buggy and crashed when I refused to allow location services. It further would allow me to make certain changes to my reservation.
