Pretentious, but not because the food or setting is above average. Some of the most plain bland chicken sandwiches and fish tacos I've ever tasted. It is very bland overpriced medium/small portions.
The botanical garden is pretty cool, and this place came highly referred as a romantic great lunch spot, but did not deliver.
It is not worth your time, plan on eating somewhere else after. Unless you like bland overpriced food and the convenience of being at the garden already.
