Hey Ron,
Couple of choices within a quick walk of Navy Pier -
The closest is the Streeterville Location of Kamehachi, at 240 E Ontario. I've never been to this particular location, but their Old Town spot on Wells was always pretty decent, with good service, a nice quiet sushi bar area, and a standard but well-presented and decently priced menu. Certainly no Katsu-esque mind-blowing Omakase gold-leaf on dry-ice infused matzoh ball eel roe goin on here, but, if you've got teens in tow, that's probably ok as well.
Of course, a couple of doors down at 230 Ontario is your namesake, Ron of Japan. Can't comment to the quality or price, as I've never been. But you could impress your daughter's friend and claim it's "your" place or something. (hey, there's a concept reaturant for you - An Akira Kurosawa-themed Sushi bar! Call it "Ran" of Japan, and have certain Omakase like the Rashomon (the same fish prepared 4 different ways) or kooky theme-restaurant named dishes like the "Seven Salmon-Roe"; a tres leches-like cake called "Akira Kurosawa's Creams"; drinks could be small, medium, large, and "Yo-jumbo"... etc... Hey, I know Trixie-Pea is Trixie-peain' her pants laughin, anyone else??? No?? OK, on with the Sushi recs before Ron kills me...)
Close by Navy Pier, at 19 E Ohio (either next to or in the basment of the Tokyo Hotel) is Ginza Fish, to which I was once taken by a real, live, actual Japanese man! Brusque service, kinda dirty/sticky atmosphere, but dirt cheap and surprisingly nice sized and fresh cuts of raw sea creatures. The place itself is a Tokyo-by way of New York-by way of Blade Runner sushi joint, in which a bored Japanese pimp (with requisite leather jacket sporting the logo, "Mustang Elvis Yankee crazy jazz time") and his overly made-up "stable", all sitting, bored, smoking and sipping on Sapporo tall boys, would seem the ideal customer base. Enjoy, Ran-and-daughter-and-daughter-friend-san!!
