I'd like to second the notion that Hazelnuts has some of the best crepes in the QC and I'll even go a step further and say they have the best variety as well. There are few places in town to grab crepes and these guys do a fantastic job.
I had tried to visit a few times in the past but my plans were thwarted by either long lines or impossible parking situations. That should probably be your first plan of attack. Unless you're a briefcase-toting Uptowner or just so happen to find yourself at 200 S Tryon...by happenstance, then you'll have to make the blessed trek of parking. If it's just for a meal, do your damndest to find a meter on 3rd or even out front on Tryon. God speed to you!
The crepes themselves? Hard to say about the thin layer of crepe as the varieties we tried were masked by some awesomely pungent flavors. With that being said, I'm sure you can order a more simplistic crepe if you're in the mood for au originale. For those craving concoctions, the Chipotle Chicken and the Mariachi are rather tasty. Though stuffed to the rafters with foodstuffs, it's a nice breakfast or lunch. I really dig the chipotle chicken, but it did have lettuce playing second fiddle to spinach. Really? Not a fan of that at all. Lettuce does not hold up to heat nearly at all and it made a limp mess inside of my crepe.
The prices are pretty fair for the amount of food you get. I think most would be full after one stuffed crepe. I couldn't finish mine or the one we shared.
Glad to have finally tried Hazelnuts. Great folks over there.
