Whilst the app has largely not been updated since Fright Nights, a listing for Sombrero's has appeared at some point, which I don't recognise.
This certainly wasn't the menu up-until Fright Nights, and whilst I don't know their precise Fright Nights menu, I can't see them having changed for the last month so dramatically.
So could Sombreros be saved? It's also interesting to note it's one of the only Thorpe managed did outlets to not be listed as peak-only, and accept cash.
Also, from the post above: yep, definitely avoid Pizza Pasta at Thorpe (and most places actually).
