Enrico Biscotti is a wonderful little restaurant and bakery in the Strip District. The biscotti is made fresh daily so it is fresh, soft, and flavorful rather than your typical hard and stale. There are other hand made Italian confections as well if you aren't interested in biscotti.
The restaurant next door is quite rustic and those pizzas made in that wood-burning oven are fresh and warm.
I have never tried their baking classes but they sound very interesting and I plan on doing so in the future.
If you are in the Strip, definitely stop by Enrico Biscotti, you won't be disappointed!
