Okay, I tried it today. I got the original and chili mayo, they were sold out of the curry. It's okay...nothing special. Worth trying once, but probably not a repeat for me. I prefer Japadog

They're open 11:30-9:30 every day, but sign says they will close early if sold out. It was quite busy today, and most of the customers were Japanese, so I guess that's a good sign?
I'll post pics tomorrow, too lazy to upload the pictures from my camera
