I haven't been in Norman since 2011, and The Earth was a tiny tiny shop on the corner of Asp at Campus Corners... difficult to get seating even at "off hours" but now! Not only is it bigger, but the lot (just past the old location) provides parking for any of the businesses in that building and therefore, you have free parking, too! A real bonus in this busy spot of Norman, so close to the OU campus.
I enjoy the robust ingredient offerings, and unlike another reviewer, I do not find the menu to restrictive. Of course, if you are going to compare it to a big city, then sure... but look, we're talking about a small college town (but not a small college!) that is still opening itself little by little, and therefore, I do not compare this to larger cities I've dined in.
I find the offerings well-thought out: it is still catering to a small percentage of people in Norman, which is already saturated with restaurants (and car dealerships!) so they can't possibly maintain quality and freshness with too many selections. Check out their menu online, you will find something to please you.
Their desserts are very delicious and the staff I encountered I found to be friendly, inquisitive without being intrusive, and made me feel at home. (I was dining alone this time.)
Norman used to be a healthy-food wasteland, a vegetarian desert. No more. I am about to write reviews on a few other oases in this growing little veg-friendly core in Norman.
Get yourself to the Earth Café and Deli... you won't regret it.
Cons: Very busy location at Campus Corners
