Great burger chain, I just hate this one particular restaurant that's on the strip.
Dirty on the outside and horribly crowded on the inside. You'll see all sorts of people in the inside from the business professional to the dirty street hookers. What's important is that they're actually pretty well behaved since they've all walked off the alcohol I guess. This place is crowded as hell and it will take you a while to get your food.
I ordered the king burger and a peanut butter shake and ate it all. The food was great but the waitline was just way way too long. We should have just gone through the drive through and then sat inside or something. (This technique works well at crowded In-N-Outs.)
