My cousin Kevin got married a couple weeks ago in his hometown of Los Angeles, and all of my Mom's side of the family flew south to attend. Amanda and I had a little time outside of wedding festivities to sightsee. We crashed at Stay on Main, which was a hostel-like setup with private rooms and shared bathrooms. It wasn't luxurious but it was cost-effective for staying downtown.
We ate a couple times at the Nickel Diner.
Amanda loved the Flower District.
