I heartily second La Poeme. Our crepes were very tasty, but that place has an atmosphere that makes it truly unique. It's a wonderful place to let an afternoon slip by, and they serve the best homemade bread (sort of sweet, sort of savory) and herbal infusion teas.
Dean & Delucca on Prince and B'way now has freshly made crepes to go. Both savory and sweet. I've only had the sweet and it was nice. I could see that the chef making them really took pride and care in his crepe creations. They sell from 4.50 - 7.00 depending on how many indgredients you want.
