I'm not a vegan, nor do I ever eat healthy, but there is something very charming about 24 Carrots.
A lot of people think that eating healthy means sacrificing good flavor, but that is not the case with 24 Carrots. I'm a HUGE fan of the lemonade, and the variety of muffins that are available.
24C has free wi-fi which makes studying/working there palatable.
Highly recommended.
