Just read the scorching (pardon the pun) review of Bonfire in the Phoenix and started to wonder about how many visits you should make to a restaurant before reviewing it. Robert Nadeau only went twice to Bonfire. Is that enough? I know we (regular chowhound-type folk) don't have the time or luxury to always visit a place multiple times but it does bother me a little when I see someone here or other places, trash a restaurant after 1 or 2 visits. What do you guys think? Just curious.
