If it weren't so all-fired expensive, I'd go to Rollier's all the time. Their staff is friendly and knowledgeable, they have enough extra fun stuff (candy, Papyrus greeting cards, candles) to almost feel like a variety store, and a parking lot on Washington is definitely a luxury!
The main drawback is that their prices are high. I support them as much as I can, with the purchases where I can afford to spend a little extra.
