Ésta / Esta
This (one) is very delicious for a cheap hot dog.
Ésta / Esta es muy deliciosa para una salchicha barata.
I think there should be "Ésta" but i saw this sentence written with "Esta".
Could you, please, tell me which one is correct? ("Ésta" or "Esta" in this sentence.)
Thank you very much.

esta - "this" before feminine nouns: esta manzana, esta mujer,...
ésta - "this" used as a pronoun to refer to a feminine noun: Mira ésta. Coma ésta.
- but apparently since I think around 1998, the powers that be have deemed the accent unnecessary unless the meaning is ambiguous so esta is fine

The both mean the same thing (this), but as Kiwi says, you no longer need the accent mark.
