The Jersey Giant was a bit of a Diamond in the Rough. It's definitely firmly in the category of dive bar...that dingy, damp, darkness that greets you as you descend into the basement makes that unmistakable.
What was also unmistakable were the excellent prices. They had a burger and fries for something like $7 or 8, and it was in fact a good burger and fries. They also had some decent pints on special for $4.50 or something like that. I was overall pretty impressed with the food.
The quality of the service was also pretty good. We arrived after having had yet another douchey experience with the hostess at C'est What where she tried to put 7 of us in a table that seated 4 and most of the other open tables were somehow "off limits" for one reason or another. The waiter at the Giant took great care of us, bringing us sample beers, etc. He did disappear for a while when we wanted to pay but was otherwise quite attentive and friendly.
I'll definitely be back to this place sometime. The overall experience was pretty good.
