Before the pandemic there were other msc that offered a nice amt of sit down dining shops but it seems like these are few and far between these days. ACL shops in 2019 did not fly off the shelf in my area but in 2023, just as you say, they are all taken before I even wake up. So it seems the solution is to wake at 3 AM and check every single day! That said in my big city there were about 25 shops listed yesterday and all of them were for July 9. All taken too. The rest of the month is still to come I guess.
For a city of 9+ million people which I assume has thousands of shoppers that is a lot of competition for their dining shops.
