This place is convenient for me because it offers delivery service and is between my office and home. I've done both Delivery and AYCE. I will go back to this restaurant for both any time I can.
Delivery service:
I get the impression this is not their primary function. The driver I suspect is the owner, and he's nice enough. To be honest I try to make sure it's worth their time, and my delivery orders are almost always over $60. I use the eat24hours.com service to order. It's not the fastest service, the quoted time is 45-60 minutes, and I've have it delivered at 75 minutes once. When they are not busy I've received the order once at around 30 minutes. Overall I'm fine with this, as I said it's not their primary function. Infact some might consider delivery sushi a sin.
Order process is a little limited. This isn't the fault of Arata, since we go through a 3rd party. They do follow notes and comments on rolls and upgrades.
Presentation is always good. I order deep fried rolls they come hot and the taste is always great. Now with that in mind my hot rolls come packaged with cold rolls or sashimi. I can deal with luke warm fish. So normally it's not even a concern. I had have luke warm sashimi and I've re-chilled it for comfort before. They usually include extra sauces at my request on the notes. I dont have to pay extra for basic requests. Also they write the names of each roll on the packaging which is helpful for beginners.
As for the quality this has also been great. Taste is amazing and the sauces are adequate, and not watered down. I've never felt shorted by different items. I have not really enjoyed crab, then again I avoid it where possible from ALL sushi restaurants so I can't fault Arata.
AYCE service:
Only done this once. It was pleasant and I had no issues. I sat at the bar and the service was quick and they provided everything I wanted. Taste as always is amazing. The chef I had was new he was a little unsure of himself, but the experience was fine, and he tried hard on the rolls. Which I deeply enjoyed the experience. There are other AYCE dinning options around and I try to branch out when possible. Though there was nothing wrong with this location.
I will do both services again. I am deeply thrilled with the delivery service.
