It's all about
PINK'S if you want a restaurant dedicated to hot dogs. They've been around since 1939 and have the best dogs in LA. They make their own dogs, and have a family recipie for Chili. If you visit this page, make sure you check out the star photos.
I've never gone by Pinks without seeing a line outside. I've seen lines at 1am.
Check the Menu too. Good stuff. I like the Guadalajara Dog. They also serve Orange Crush, Nehi, 7-up, and other sodas in glass bottles, which I didn't even know still existed.
Good stuff.
