I was in Hiroshima and found this little Tex-Mex restaurant near the bomb dome. It was great, and I say that as someone originally from Texas. Search for it if you’re ever there.
Weird note, if this is the one with the cowboy hats on the wall, the woman who owns the place was a child when the bomb was dropped and she will tell you about her memories of it... Both of her children died of cancer in their thirties. She was in her late 90s... Maybe she passed away by now. I was there 15 years ago...
