1. Neither of the restaurants is my expensive.
2. Neither of the restaurants are expensive.
3. Either of the restaurants is fine.
4. Either of the restaurants are fine.
5. I was invited to two parties last week but I didn't go to either of them.
1 and 2 are both grammatical and I wonder if sentence 4 is grammatical too.
Also I want to know why 'both' can't be used in the sentence 5 instead of 'either'.

To use "both", I would expect to hear something like "I was invited to two parties last week but I didn't go to both of them - I only went to the one that was a five-minute walk from my house". You are simply making it clear that you chose to go to one, but not both.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
