Update: I've called and secured a reservation for 7 people at 10 am this Sunday.
I've been looking for a French cafe in Madison for ages and finally stumbled upon La Kitchenette. This place has an extensive menu: facebook.com/pg/lakitchenettemadison/menu/ including crepes, salmon, croq' monsieur, salads, french toast, etc. I'm looking forward to getting to try this place. I will call tomorrow to attempt to book a reservation for this Sunday around 11 am. If I can't book for this Sunday, I will try to get more information to determine an appropriate number for the event size. For now, I'm going to keep it at 6 people in total.
