I recently remembered eating at an impossibly charming vegetarian spot called Balasia in the Lehigh Valley some years ago. It was amazing and the aesthetic was perfect. I am sad to read that it has since closed. Bummer!
If I'm not mistaken, she opened up a new spot, called the Honey Underground.
Also in the Lehigh Valley is Alando's Kitchen. It's Kenyan food, with TONS of options from what I understand. I've never eaten there.
