We have dined 5 times here since spring of 2012. Each time has been different in the menu at least by 60-70% of courses. Unfortunately, our last visit was terrible and dissappointing from both the service and taste that we feel sad that Alinea and/or Chef Achatz may be losing his goal of pursuing fine dining service and food perfection. Only two new courses were done to perfection while the rest, even my favorites were either under seasoned or lukewarm such as the truffle explosion. One "main" course everyone finished eating before the wine pairing was poured and that was after we had to remind them as they cleared our used silverware and dishes for the next course. Without a doubt, we believe this is a sign of decline in a star and can no longer recommend this restaurant worthy of a special trip or journey.
