I would say " I'm going to the playa wanna come with me?" when they don't understand that playa means beach I just say you're loss and go.
Visité un restaurante Mexicano muy bonito
Ordené un plato de pozole
Le pedí al mesero que me trajera un refresco
Mis papás pidieron enchiladas y tacos dorados
Ser and Estar both mean TO BE.
However, 'ser' is used in permanent situations, e.g: Soy alta = I am tall. Which is quite permanent because I cannot change the fact that I am tall.
'Estar', however is temporary situations, like mood. e.g: Estoy cansado = I am tired.
Hope this helped!
