Hot and sour soup.
There's a hole-in-the-wall Chinese place right by my house, and they have a FANTASTIC hot and sour soup. Best part? They have a giant trough of it (64 ounces) for about twelve bucks. It's loaded with shrimp, pork, tofu, and egg. I haven't the foggiest idea how they could possibly keep from losing money on it. It should cost about $20, and I'd still feel like it was a deal.
