Ai Sushi is my favourite place to get takeout sushi. However, the wait can be long if you're walking in and ordering. On a Saturday afternoon, I was told that it would be 20 minutes (as everything was prepared fresh) but it was more like 35-40 minutes. This was kind of irritating as I was in a rush to bring this to someone's house for dinner.
More about the food - the maki rolls are great and the sushi rice is flavoured well. We don't eat tuna so we were able to substitute that with salmon. The colour of the salmon was a little off, but it tasted fine. Perhaps it wasn't as fresh that time? The presentation is nice; great if you're bringing this to a gathering. The sushi platters are also very reasonably priced, but note that it's cash only. This kind of annoyed me as I'm someone that never carries cash.
There are a couple of tables but everyone that's sitting down is waiting for their take out order.
I noticed that one of the sushi chefs was sleeping with his head down on the table in the back corner. I thought that was funny :).
