The first (and only) time I've been to Marble Slab before this one was in 2002, when I was in Greenville, South Carolina. This was before the days of Coldstone and other mix-in spots, and boy was it a novelty! Marble Slab seemed to bypass other places I've since lived, and while Coldstone is similar, there's something nostalgic for me finding a Marble Slab.
There was only one guy working the counter when we arrived; then again, we were the only customers since it was snowing out. He took our orders one by one and mixed in to perfection. The prices are higher than other frozen novelty places where we live (in the states) but that's one thing you forget when you don't live here.
The vanilla ice cream was really smooth and didn't have the cloying aftertaste that sometimes accompanies vanilla ice cream. I liked the cookie dough mix-in. Jon got one of their specialty mixes and also liked it. The standard includes a waffle cone, though you can upgrade to a waffle bowl if you so choose. Two smalls with 2 mix-ins each will run you about $6, inclusive.
And, for the record, a small is more than plenty!
