Culvers we usually get a Family size Onion Ring and Family size curd.
Though it has been a while my daughter usually wants to go there for our monthly dad/daughter dinner on the way home from her guitar lesson and band practice, which is 45 minutes away. Sometimes we also go as a family to the one near our house which opened up in the last year.
The double bacon cheddar thing they have is good. The Buffalo strips were good but they no longer have those (at least at the ones in this area) and only have the original chicken tenders, which are not great. I'd rather hit Zaxby's or even better Raisin' Canes for chicken tenders.
One nice thing about Culvers is they have a few choices for sugar free drinks including root beer. Most places have diet coke or pepsi or the "zero/free" version and that is it.
