I drank one while flaming once it didn't burn too bad in the mouth but I had a mustache at the time which got a bit singed lol.
Flaming Dr Peppers are real good... IF you are a guy and have a mustache or a girl with long hair be aware of the sizzle though lol i seen many people get toasted....
They use to make a row of the @ La Boom....hmmmmm the memories of La Boom. Tip your bartender at your hotel enough, he'll make em!
