I visited two locations of NF during a recent trip to Chicago. Unfortunately, I found this one did not measure up to my experience at the LA (Westwood) location or at the Chicago (Wicker Park) location. The food was good. I ordered the tacos. Perhaps it was foolish to expect LA-quality tacos in Chicago. The tortillas just did not taste the same as LA tortillas; the fillings were okay.
The teas were very tasty, and fresh mint leaves were available. The have free refills on drinks.
My (non-veg) mom had ordered too much food, so I was able to taste some of her leftovers. She ordered a giant salad with tons of avocado. The salad and dressing were good, but I rarely order salad in a vegetarian restaurant (that's what I have to buy from "meat" places). The edamame hummus was only so-so. My husband ordered the bacon cheeseburger, and it was very good.
My mom was staying at the Hyatt a block away from the restaurant, so the location was ideal, in a strip of new businesses that have sprung up in Hyde Park. It is really close to the 53rd Street Metra Electric commuter train stop, which was good, since my husband and I were staying at a hotel near O'Hare, and all of us were without a car. If you are visiting the "South Side," this is a good option.
Cons: tortillas just not as good as in LA
