How about that new place on the lake, Spencers. Not sure if it is romantic. Heard its a little pricey, but at least its new.
All other places on the lake are more meat market oriented..
Great food but not a romantic drink type place. Check out The Martini Bar (something appealing about a place that specializes in serving straight alcohol). Pepperwood is decent too and has a better ambience for a drink than Sonzi.
