I booked a Betty Lou private cruise on Lake Monona for my Mother's retirement party and it was great. She loved it, which was the most important thing. At $19 per person the open bar is a great deal. The food was pretty good too - we ordered the basic appetizer setup and it was actually really nice. It starts with chips and dip and moves into mini sandwiches and some slightly heavier items. I also thought the boat was really cool too - there is an awesome covered outdoor area upstairs and a cute sort of throwback loungey area downstairs where the bar is. The service was really great and the staff were laid back and fun. The Betty Lou is almost a Madison institution and I highly recommend a private cruise for a special event.
