It is difficult for me to rate Flower Child on the 5 star scale. I've eaten there about 5 times. Some observations:
1. You can eat there for a decent price IF you are careful. Drinks and desert add significantly to to bill. Note prices carefully
2. This place suffers a bit from being overly hip at times - all the cookies are gluten free, for example. Their name, a throwback to spoiled suburbanite college students in 1967, seems appropriate.
3. Why no unflavored black or green iced tea? Flavored teas make me order water only. Again, trying too hard.
4. I once got a very sandy salad. Sure things like this happen now and then. What I don't like is when the server becomes defensive and offers excuses when I politely told her about the sand. Yes, organic lettuce might be more sandy, and, yes, if you know that then wash it more carefully.
With places like Mad Greens and Grabba Green in the area serving great salads at lower prices, Flower Child has its work cut out for it.
Bottom line: overpriced and perhaps missing attention to details. You can get better for less money and also drink unflavored tea. Probably not meeting the overall quality you'd want at this price point.
