Chili cheese fries and burgers. Took my vegetarian sister here and she even found things to eat and thought it was good. A must visit every time I'm in the LA area.
Garden burger is great but apparently staples such as the dogs and chili cheese fries regn supreme. Fast, delicious and definitely get some lemonade while you're there. You're welcome!
Skip the shakes and order a second hot dog - much better value for money. The New Yorker hot dog is a classic, but I personally recommend the Red Baron.
Last time I went I tried the spicy tuna melt for the first time. If you don't want one of their awesome chili burgers or hot dogs, try it. It's damn good!
