I think there's definitely room for a decent punting webapp. I see that you've got rates n things listed.
How is all this data stored? Would be neat little project to allow you to filter, by price etc.
Then all you need to do is approach the shops, and give them a little login where they can set daily prices/discounts, happy hours etc
that then put them at the top of the list for price, and you've got something great.
Add a little chat thing where people can chat with the girls, so they can lure customers in and theyl'l be happy even if it's an LLM doing a lot of language translating.
There's a lot of room to innovate in this sector, especially here in Aus where it's legal.
