Is it Asplenium nidus ?

Hello, yes, I am pretty sure it is “A. nidus” (A. nidoides Fraser-Jenk. & Kandel) and not the closely related A. phyllitidis. Both are known to be present in Sikkim.
But actually we simply must see the sori under the frond, to distinguish definitively between A. nidus and A. phyllitidis– and your photo doesn’t show any sori!

I agree with Asplenium nidus

Yes, it is Asplenium nidusBirdnest Fern.
