United Noodles is definitely one of the best Asian groceries in the Twin Cities. however, even though it is fairly large, they still seem to abide by the unwritten law governing Asian groceries (and co-ops, for that matter), which states that there is always at least one of your favorite items that they don't have, and that at least one other Asian grocery does have. for example, Shuang Hur on Nicollet has some fake meats that United Noodles doesn't carry. and vice versa. so if you enjoy and have time for an afternoon of leapfrogging around to 3 different places, this isn't really a big deal; but at times it'd be nice to have a complete, one-stop shop.
one of the things i especially like about United Noodles is that their selection of dishes and bowls is unique, elegant, cute, and seems to be of a higher quality than other stores. and, of course, like everything else, the dishes are very inexpensive.
another nice touch is that they provide green tea to drink as you shop! it's probably best to peruse those ceramic dishes before you get all caffeinated, though.
