I disliked the fact that they automatically added gratuity. It greatly reduces my return to that restaurant, based on that fact. There are so many amazing places to eat in the city that don't include gratuity. Maybe it isn't the fact that it was added automatically, but that it wasn't pointed out, as if I would have left more based on not reading the bill. Since, the waitress wasn't even very good, perhaps I wouldn't have left 20% - at one point the server was chewing/eating while at our table.
The food was good, but too bad the service was so-so; and I'm being generous.
