You can not go through Lebanon without stopping by Whit's for a cool down. The "Custard" is absolutely amazing. The atmosphere in this place is fantastic. It has the old time ice cream parlor feel right off of the main street in Lebanon. Inside the employees are helpful and you can sit at one of the tables or grab a stool along the wall. The custard is delicious....extremely creamy and much smoother than normal ice cream. I think I had the Caramel cookies and Cream last time I was there and it was to die for. The prices are pretty good here and I've never had much trouble finding street parking to get it.
If you go through town here and don't stop then you are really missing out.
