From my own personal experience:
If it is something I am going to do a formal review of, then I try and visit the place at least twice.
This gives me a double check, and to try things I didn’t try the first time, and to become more familiar with the place/history/foods/owners.
I have found places that the first time, I thought the place was awesome, the second time I went back it was like Jeckel & Hyde.
This is just me though, I can’t say for everyone else.
