Central Cardiff in 25 mins per Google, but best allow 30. Refresh, Marigold, Patty should all be doable in this sort of time if you avoid peak traffic. All these are Thai and will do extras. Ask in room.
Nice but very legit Thai one in Talbot Green is not far.
I think the Ponty one is an offshoot of Gigi Chinese near Roath Park in Cardiff. Don't know if open. If you are lucky you will get a youngish pretty Chinese female.(Avoiding saying girl for fear of mistaken meaning - obviously over 18, but younger than the Thai ladies usually are).
