My wife and I went to a new, high profile restaurant recently and were seated at the "chef's table", which was actually the counter in front of the open kitchen. While the restaurant is clearly still working out some service kinks, the food was decent.
What wasn't cool was watching the chef/owner tasting everything with the prep utensils or his fingers and then continuing to use those utensils, or his fingers, to prepare the food. My wife was freaked out, and finally said something to our server about it. This was not just hi-temp dishes like sauces, but we also saw him tasting dressings on salads with his fingers, then go back to prepping the salad.
We also noticed some of the line cooks tasting food with spoons held in water-filled pots, which were then just dumped out and refilled with water -- but not cleaned in any way.
This just seems unsanitary, and I remember seeing an episode on Top Chef when Tom Colicchio busted one of the contestants for doing pretty much the same sort of unsanitary tasting.
I can understand this is one of the drawbacks of an open kitchen, and that most guests would not have seen it, but should we say anything more? What would you do?
