I decided that I had to upgrade my review from my very insulting original review to 5 stars. My wife still spoke admiringly of JAMcafe two weeks after going. She really liked the duck confit, the potatoes it was presented with were prepared in a special way, and the sauce was special. In addition, she appreciated how the chef came out to ask us how we enjoyed our food. But it still took 1 hour to get the food.
Apparently, my original review was so insulting that I got an e-mail from a yelp staffer in San Francisco telling me it had been deleted! But all is forgiven.
