I love the coffee bar at Harvest. Staff are fast and courteous, and they make a really good coffee drink. (I get espresso-based beverages and can not speak to the drip coffee.) I appreciate that they do a "buy 10 drinks, get 1 free" card. It gives me a little more reason to stop in before work instead of fighting the drive-thrus.
It's neat that they have a gift/shopping section on top of the groceries, restaurant, and deli. The store always seems clean and organized, and the staff are incredibly friendly.
The upstairs seating area is huge and spacious! Plus, if you can't find an item, they'll try to see if they can stock it.
Although it's a full-sized grocery store that caters to all tastes, it is a bit pricier for some items that you can buy more cheaply elsewhere. For example, I might buy gourmet or organic items here, but maybe not macaroni and cheese. Great array of items and specialty sections, e.g. gluten-free. I'm happy Harvest is in Champaign!
