food has gotten more expensive but it's not that expensive. $25 entrees is unaffordable for most people, how are you getting to $100/head at reasonable restaurants? Does everyone order the ribeye?
To emphasize, there are obviously cheaper restaurants, and given how much it costs to live in Austin, I'm not bemoaning their prices. I'm just saying that pre-pandemic I would have thought of a $100+ meal in Austin as "very fancy, special occasion" place, and now it's easy to hit that at tons of places in Austin. I used to eat out a lot more at places like the above when it was ~$60 pre-pandemic, but it's not worth it to me at $100+.
The market gives you the opportunity to overpay if you want to, though. It's not a representative example.
