"Now we're drinking Fanta; it's much better here."
mejor meansto be better.
"Hey man" doesn't translate to Spanish. You can translate the words, but the meaning of the phrase doesn't translate. A close phrase could me "Listen Man" - Oye hombre How are you = ¿Cómo estas?
"...because now it's better than ever."
Eres la/el mejor.
Translations Por lo que - For that of su mejor amigo - your best friend de aprender español - of learning Spanish ahora - now que lindo y gracias - how nice and thank you
"the sooner the better"
'No soy tu mejor amigo?'
lo mejor de la suerte
mejor amigo (or amiga if the best friend is a girl)
"Feel Better" would be "sentirse mejor" - if you a re saying it to anyone you would say "Que te sientas mejor"or "Que se sienta usted mejor" (more formal).
Voy a Mexico con mi mejor amigo
It helped me a lot because now I'm in the best math group.
