I've been here twice (2nd floor) around the same time (post midnight), and on both occasions the experience was good. The decor was nice on the eye, the lighting dim (perfect for the time we were there) and the music selection was catchy.
The menu is authentic and original and the items were made and presented well. They were definitely generous with their portions and the service was definitely on point. The staff was friendly and courteous (especially considering that it was around 3am), and made sure to ask us on numerous occasions how the experience was going. They also clarified any questions we had about the menu/place.
Out of the 6 items we ordered on aggregate from both visits we only had an issue with one (pasta) and thats only because it didn't live up to the expectations from the first time we ordered it!
I gave it four stars because I think they could do more to arrange the seating in a better manner and also because I think the menu could use a revamp (not food wise but the actual design).
I would definitely visit again and would definitely recommend to anyone looking for a good meal 24/7.
