I didn't see anything on their menu labeled sugar free from my recollection anyways, but I agree with Michael about giving them a call to confirm.
Entrees are $18 - $35. I did not see any sugar free desserts but they use chocolate for more than desserts and not everything is sweet.
Don't know went to a banquet that my aunt paid for so I have no idea about pricing as for sugar free chocolate I'm sure they have it but I didn't see any you can give him a call just Google chocolate sanctuary Gurnee on Washington Street
