We live in the area and typically visit Mars 3-4 times a year. There are fewer places in the Lake Geneva area to sit outside by a lake and have a cocktail than you would think. Mars is one of those places and that's probably the biggest reason why its always so busy. The second biggest reason is that there are a bundle of folks who live in the surrounding houses only during the summer season and...they like to party and...they don't want to get a OWI ticket so they go to the closest place they don't have to drive. You'll run into plenty of heavy-drinkers at the bar here. I'm not big on crowds and it's always very hard to get a seat at the bar here - and the bartenders seem to move at one speed - and it isn't fast. The third reason the place is busy is that it has pretty good food. The ribs a very good. Ten years ago it was a better value but prices are still very fair. This place could be an even bigger goldmine if the owners would put a few bucks back into it every decade or so - and they haven't. It's certainly in need of a thorough cleaning and updating. Still, if you don't mind a jam-packed joint and the accompanying inevitable wait for a seat and service, this might end up being your favorite spot.
