So I'm one of those Chapman U kids but alas I am not the Emo type. I completely agree with the review of Cafe Lucca. The coffee and espresso is amazing! The Gelato is fantastic (I have some in my freezer right now) however it is really expensive. If you live in the area I suggest buying a pint ($8) or a quart ($14) because you get so much more for your money.
As for Mustard Cafe. I wasn't the biggest fan of their sandwiches, I definitely prefer Blue Frog. However, I have had some tasty soups and the occasional baked good. However, my vote still sides with Blue Frog every time. Very delicious, very affordable and a great friendly place to go with friends, family or study.
