I've been to Brown Sugar a few wonderful times. Their food is absolutely the best Thai I've had in Boston. I'd go there all the time if parking wasn't such a nightmare in the Fenway. Still, for a date this is the place to go. It's intimate and the servers are fantastic. They refill your water and check in with you an appropriate amount, which is important. And the food, holy moly, it's great! I had the green curry, which was the perfect viscosity and spiciness.
Pros: food quality, service
Cons: parking
