I went and saw this last week and found it quite delightful. Got my ticket through TDF and sometimes the complimentary drinks aren't included in TDF tickets but they just walk around refilling shots (it's open seating, show up early if you want to get a table). The shots aren't full shots, I'd say closer to a third/half but they'll refill them up to around 6 times if you drink quickly enough. You can also get a drink at the bar before the show but ours were VERY strong pours.
The show itself is really sweet, it deals with the bar during Covid so I wouldn't recommend it if you feel that it's too soon, but there's a fun cast of characters and some catchy songs, and it's nice to see a different perspective on events. The ending was a little cheesy but it leaves you going home feeling good about it so I don't fault it too much for that.
We sat near the bar which is on the far end from the stage area, but the performers go up and down the aisles a lot and the bar is one of the main set pieces in the show so we didn't have any issues with sightlines (though I'd recommend being closer to the main stage if you want to see the step dancing better. I hope they get more of the songs recorded (especially Half a Pint Left). Ultimately just a nice way to spend a free evening.
