ST DAVID’S HALL will be transformed into Mexico on Wednesday 8 July as the Ballet Folclórico de la Universidad de Guadalajara visits the UK for the first time in 20 years.   It’s also a time for celebration too as it’s the Year of Mexico, and the group specifically asked if they could come to the Welsh capital!   Plus, it’s a great value night out too with a special Buy One, Get One Free offer* on all seats!  …
