Bigham Tavern is a pretty typical bar/restaurant. There isn't anything too special about it. There isn't anything especially bad about it either.
The best food I've had while eating there were the loaded fries, and the worst was probably the underwhelming fish tacos with the equally underwhelming sides of beans and rice. The loaded fries were really great and I highly recommend them if you're eating at Bigham.
Bar service has consistently been great, and I've had really good service and then mediocre service. The place isn't grimy, but it definitely is a bar...
Overall, Bigham Tavern is a good place for drinks and bar food. It's similar to a lot of other places and doesn't feel too special, but it could be considered an option if you're in the area.
