Smiling Banana Leaf was a highlight of living in Highland Park for a few months when we first moved to Pittsburgh. We go pretty regularly, almost always at off hours. We've been told at dinner that there would be a rather long wait, but they always offer to call your cell phone if you want to go to the coffee shop around the corner or walk around.
The spring rolls are nothing to write home about, but the entrees are fantastic. Their tofu is really good.
