You can say: "es muy cierto" or "es exactamente eso" "es cierto" "así es"

Hi Keitren! It feels thrilling to come across another Spanish learner as dedicated as you seem to be, so I hope you end up acquiring the fluency level you desire in the language, soon! To answer your question, a colloquial word/expression that you can use for the kind of scenario you have mentioned, is "Fíjate". As a result, you can say something along the lines of "Fíjate si la comida es deliciosa" to be able to say "Yes, the food is delicious all right" or "Yes, the food is delicious, absolutely" or anything similar. Basically, Fíjate + Sí is an emphatic way of saying that a concept, idea or something similar, is clearly and unequivocally right. Feel free to keep in touch now that it is clear that the both of us are learning Spanish, I hope that my response helps you to some degree. Also, I hope that you have a rewarding day and week ahead, ¡estamos en contacto!

Si, es exactamente eso o es muy cierto

verdadísimo

Hi. On that context: "It's very true", you could say "Es muy cierto", "Es totalmente cierto" "Yes, it's exactly like that", you could say "Sí, es exactamente como dices", "Sí, es exactamente eso" Saludos.
