Of those things that I've tried from several places, I like the Boba Tea from Blueberry (peach/guava, with mango jelly instead of the tapioca balls), and the spring rolls from the place right across from Blueberry - forget the name of it. They use real sliced pork (instead of some bologna-looking pork product - which might be good, I've never had it, though) and shrimp, along with mint leaves in the herb mix, and come with two dipping sauces at 3 for $3.
I've also had pho in two of the places, and one was good, and the other was below average, so I wouldn't really recommend either of those.
I took my daughter along last time, and she had "drunken noodles" from one place - I can't remember the name - it was near the middle, and it was, I think, the only place that had drunken noodles on the menu. They were _really_ good - I'd recommend those - kind of a slightly spicier version of chow fun - very tasty.
Sorry I'm so bad with the names, but some of the places aren't that well-marked, and I'm pretty sure some of them have also changed names between my visits. I'll pay better attention next time - I usually just wander around until I see something that looks good that day.
