The speaker said "esta" . I thought "plato" was masculine, but it sounded like she said "esta", so that is how I spelled it. However, when it was wrong, I listened to the slow version and she sad "este" I really need to learn not to trust her pronunciation, but to trust my instincts...
One of the accepted answers should be: "Are you trying this plate?" It is common usage and understood by native English speakers such as myself for "plates" to also be considered meals. What comes to mind is a literal "plate" of food. Yes, it can refer to the object, but it can also refer to meals that fit on plates. Please fix this, ¡Muchas gracias!
