Inn Season deserves a hearty second - it's been around forever, and they really do an amazing job. It's been there so long that I can't really remember for sure in which decade I discovered it - but I think it was the late 70s.
Not vegetarian, but I would add Thang Long in Madison Heights (on John R , maybe 1/4 miles south of 12 mile on the west side of the street in an older strip mall) as an essential visit if you like Vietnamese. I do, I've eaten in many Viet restaurants, and I'd say it's the best Viet I've eaten - BIG push on fersh herbs! jeff > > In Royal Oak, off Main Street: Inn Season (500 E Fourth). Mostly very, > very good.
