There are still some kinks to work out, namely that for now the reservation cheat only works when using Yelp's phone app and not the full desktop site. Yelpers are also unable to filter out joints not yet participating in Nowait's program, so they’ll have to seek them out on a case-by-case basis. But seeing as it was just released today, we'd bet updates and user-focused improvements are on the horizon.
Unlike folks hoping to score a spot on the list, participating restaurants must agree to a monthly fee in order to use the service. You're able to cancel your reservation online, and if somebody ends up being a no-call no-show, the host just moves along to the next person in line, analog-style.
