Pretty good if you are hungry. This place is probably still good if you are just a tad hungry. Having raised 2 kids myself, I would not consider this a toddler or up to 5 years old kid friendly place. You are going to spend your time corraling them here and not eating what you ordered.
I was pleasantly surprised at their accommodations for food allergies ( gluten ) and their super cute souvenir items for purchase. ( which makes it hard to keep small kids seated) Expect a moderately to slightly overpriced pay for what you order. Don't be taken off guard by the valet parking service, which I found particularly odd considering the diner's atmosphere is extremely casual.
