I would recommend going to Landry's Select Club website and joining. Once you have a select club number you can call Yak and Yeti directly and make a reservation or you can do walk up. With the Landry's Select Club membership you don't need a reservation, you just walk up and show them the card and are seated, normally within about 15 minutes. We have eaten there several times and never had a reservation and never waited more than about 15 minutes or so.
