Duke of Kent is a cool pub, with good food and reasonable (although not bargain-basement) prices. It can get pretty busy on the main floor, but the second floor is quieter and roomier if you are less interested in socializing (or just want to be able to hear your date).
Service here is solid and the food is reasonably high quality (by pub standards). I can recommend the chicken pot pie, the club sandwich, the burgers, and the sweet potato fries. There is a decent selection of beer on tap as well as wines by the glass.
Dinner for two with a pint each will run you about $50 with tax and tip included.
