For what it's worth, me and a friend had great sushi (and i don't even particularly like the stuff) at Mairi (sp.? -- it's on Division St.). Several kinds of the best tuna i've ever had as well as softshell crab "cocktail" that was also supremely fresh with excellent, unusual flavors. Mainly, though, Chicago critics are always carping about the snooty service, and we were treated very well. We actually arrived before they were ready, and they let us linger on the soft furniture in the upper-floor bar and drink wine. The young servers were friendly and polite. But then again we're pretty easy. Unlike, i suspect some of the egregious yuppies that started to fill the place as we were leaving. Pricey, but some of the best sushi around, and given the service, worth a try.
