And unfortunately for the less enthusiastic point of view:
With this place about a two-minute walk from home, I knew I would have to give it at least one shot. And last night was the one shot it ended up having. I visited last night (a Saturday) with a friend and while I was in the mood for nigiri, I noticed that it made no sense for me to go the by-the-piece route when the all-you-can-eat featured almost all of the same pieces at about the same price (plus many other options, including salad, soup and hot appetizers). I was still skeptical of the quality of the fish at the price offered. While it is true that almost everyone gets their fish from the same places, that does not mean that all places get the same quality fish. Just like it is true that both high end and low end restaurants both use Sysco and the like.
Indeed, I found the nigiri to be of lesser quality than your average Chicago sushi spot -- some pieces of fish were too dry, some too wet, many poorly cut and some just didn't taste like the fish I thought I was eating. The rice was too sweet yet surprisingly not terribly clumpy. None of the pieces had any wasabi. You get the point -- I just wasn't pleased with the nigiri. We tried a couple of maki and they fared slightly better but not much.
I will admit that I'm a sucker for that ubiquitous Ameri-Japanese salad with the gingery dressing that I first tried years back at Ichiban and Ron of Japan in Northbrook. The salad at Tokoro is along the same lines, though perhaps cheaper. And since they rinsed but did not dry the lettuce, the dressing was unfortunately watered down considerably.
Service was also a major issue. If you wanted something that came out of the kitchen, service was prompt. If you wanted water, no problem. But with only two sushi chefs and a packed house, the wait for nigiri/maki was almost unbearable. We waited just over an hour for our nigiri and maki (for two persons). And from my observations, this appeared to be typical.
Now, not everything about my Tokoro experience was bad. I liked the decor just fine although the lighting was a bit bright for my tastes. And everyone there was quite friendly. More importantly, my favorite item of the night was the order (two orders in fact) of the fried sesame balls filled with red bean paste. While I highly doubt they make them in-house, they were not far off in terms of quality from the larger ones you'll find throughout Chinatown, just smaller and with the red bean paste perhaps a tad sweeter than my favorite versions. But even for $21.95, I was yearning for a better meal than simply tasty sesame balls with red bean paste.
