Yelp totally botched my restaurant reservation. It was supposed to alert me when to join a wait-list. It failed to do so. Then when I did it myself (1.5 hr ahead of seating time), it mis-reported the wait time and prolonged my wait by another hour. So much for hosting friends from out of town. Never using Yelp again. Restaurants, quit using Yelp to schedule your wait-lists.
