Being in walking distance from Churn is a dangerous thing. Between my boyfriend and I, we go through 4-5 punchcards a month. My ice cream usually doesn't survive the walk home...because I practically inhale it. We might have a problem. But the ice cream is so good! My favorites are the butter pecan, coffee, and plain old vanilla (with the addition of peanut butter cups). There is also always a few rotating flavors, so make sure you get them when you can because they tend to go away quickly.
If you're not an ice cream person, there are also baked goods, candies, and fun little toys to bring you back to childhood (slap bracelets anyone?)
I have to agree with others though...the parking situation is awful. Even if you find a spot, you usually end up getting stuck at the valet station while they are helping other people. You might be better off parking in the neighborhood and walking. Your thighs and sanity will thank you.
