Here’s a great way to get me to go check out a restaurant: Tell me it’s a little ethnic hole in the wall run by an immigrant family making the stuff they ate at home. I’m a sucker for that sort of thing. If one person says this, I’m intrigued. Two say so, and I want to go. If a handful of folks I trust are saying so, then I will be there. Most of the time that works. Not so with Bahn Thai (4646 Park Blvd.) in University Heights.
