NJBeen here three times ....the first time was on valentine's day and they had a special coursed meal. I thought the food was delicious and would definitely come back. I visited roka a second time and my girlfriend and I ordered for ourselves but found that the food lacked the magic from the first time. Finally we went a third time and while it was good, we just didn't find it was worth the price.
some things we had tried..
butterfish tataki - definitely a good appetizer highly recommended
prime flight - pricey item, good but not worth the price
sushi- once again good but not anything out of this world
don't get me wrong it's a good place to eat but when you factor in the price there are better options
