One of my favorite local places to have a drink is Manhattan Steak and Seafood. Located in a rather obscure part of the city of Orange, in Orange Co., CA, it is a great hidden gem well off the beaten path. The food is excellent, the staff is awesome, and the ambiance is comfortable and classy.
But this is a Martini Blog. In short the Martinis are really quite good. But just not quite great. On the plus side the drinks are generous and nicely mixed. And always served with a smile. On the down side the drinks are not as chilled as I would like, probably because the stems are not pre-frozen. Or even chilled in the refrigerator.
However, the restaurant is definitely worth going a bit our of your way to find. http://www.manhattanoc.com/
