I've been to Aqua Sushi a few times for the sushis, and I have to say what you get is fine.
The restaurant is very clean, the staff very professional and the food is fine. It is not extremely good, but it is fresh and tasty. The service is quick and attentive, while remaining discreet. you'll get to enjoy sushi while listening to Vietnamese music. Tell me about globalization! The prices are fair, and I would recommend taking their combos as they are the best price-quantity ratio.
This place is the spot if you are looking for a quiet evening without any fuss. Relaxed and simple, this is a restaurant you come to if you are out of ideas or if you are in the area.
