How do you say "can i eat that" in brazil?

Question

if you're at a dinner table and you want some item off a plate

Answer 1

Well if you were in Brazil you would be speaking Portuguese, so you would probably want to be a little more formal and ask "Could I have a bite?"

Poderia eu tentar uma mordida daquele?

Pretty much translating to "Could I have a bite of that?"

Answer 2

"Eu gostaria de pedir este aquí !"  (I wpould like to ask that plate) ou "eu quero este" (I want this) or  "traga-me este, por favor" (bring me that, please) or "Pode preparar este, por favor?" (May you prepare me that, please?).

Answer 3

Posso provar?

Answer 4

Eu posso experimentar, por favor?

Answer 5
