Hi omni board!
I just wanted to ask you a question... is it correct in english to say that "that restaurant serves also fish"?
My doubt is about the verbe to serve.
Thanks in advance

There's no problem with the use of "serve" in that sentence, but the placement of the adverb is unidiomatic. It should be "That restaurant also serves fish".

Ok thanks.
The person who is supposed to teach me english didn't know that.

Didn't know what, adverb placement? That seems to be one of the hardest things to get down. I couldn't tell you the rules myself, just what "sounds right" and what doesn't.

No, she didn't -err- doesn't know I can use the verbe "to serve" that way.
