Many reviews I have read of Martini House (on other websites) have negative reviews about service or attitude. I will state right here that I have never had bad service in the eight or ten times I have eaten at Martini House (in the bar or the main dining room at both lunch and dinner). I have always been pleased.
That said, the food is fantastic. It is a bit overpriced, but so is just about all of Napa Valley. I adore the butternut squash soup, the venison, the Sonoma duck breast and the potato rosti (I am thrilled to see it back on the menu!). Todd Humphries is a fabulous chef as well as an accommodating one (says the girl who doesn't like mushrooms but loves all of the menu items that includes them) and is very kind to the patrons sitting at the kitchen.
Trust the sommeliers...they are good ones ;)
