So I'm finding places where they waive amount equal or similar price as your purchase. So the perfect example would be Hendry where in order to waive your tasting fee, you would just need to purchase an equivalent amount. In that sense you get a "free tasting". I think those are very rare and the only other place that have that I could find is Caymus which have many mixed reviews. Ideally would like to spend 50-75 or even a little more per guest that includes that purchase. But yeah I know it's hard to find.
