We keep finding restaurants that charge sit-down fees... after we ask if there is a few to sit down.
Seriously? Weird...
This was one thing that drove me MAD in Paris.
Virtually every bar seemed to have really annoying pricing. From about 5-7 they'd have a happy hour where it was quite cheap (say 1.50 in pounds) per pint wherever you were. But after that, an entire range of pricing would kick in, where if you were standing at the bar it would be about 2.50, if you stood at the bar with an albatross balanced on your head while dancing the tango it was a bit cheaper, if you sat in the red seats it was 3.50, and if you sat in the blue seats it would be 5 pounds, etc.
I have found a thing in some Chinese-style bars here (the sort of glitzy yet seedy places that only Chinese people attend, not expat bars) where you pay more according to where you sit, but it's more a case that you are compelled to order a larger amount of drinks. The actual price remains identical.
