Subject: San Miquel de Allende

I will be traveling with two friends to San Miquel de Allende for one week during the Day of the Dead celebration (October 31th through November 7th). We will be renting a house & as part of the arrangement, a local woman to cook breakfast & lunch. Does anyone have any suggestions for places to eat & interesting places to visit both in the town & surrounding areas? Also, any particular precautions, especially regarding food/illmess etc. Thanks
