Hello!
I work pretty close to Whole Foods so I frequent it about 3-4 times a week for lunch. If you're there M-F between 12-1, you can find me in the salad/bread area (on the north end).
Compared to other Whole Foods I've been to, I would actually rate it a 3 but considering I do not know of any other Whole Foods around, I thought it's my duty to those that do not know about Whole Foods a chance to give it a try. If the zucchinis at Market District looked a little weak, give Whole Foods a try. Plus their pre-made food is actually yummy.
I'm able to keep my lunch on a budget by only buying lettuce and chicken from the salad bar (typically under 1/2 pound). I stash dressing, cranberries, and cheese in my office. I've tried buying the bag of pre-washed lettuce but I never finish them and I hate seeing them go bad. $3 lunches isn't bad at all.
Other notes: The tofu chicken is really good (part of the salad bar)! It's not always available though. Also, none of their bread varieties impress me. I like their sushi rolls. If I could afford $8/day lunches, I'd probably have it everyday. I'd give their cashiers 5 stars. =)
