Louie Mantia’s got a good system for rating burgers on his new Burger Digest blog:
One-star ★ burgers are the ones I’ll eat again, but only if I’m nearby. Two-star ★★ burgers are burgers I’ll come back to again and again. And three-star ★★★ burgers are the ones I will happily go out of my way for.
For years, I’ve been partial toward the Netflix-esque 👎 / 👍 / 👍👍 system, but 0-3 stars works quite well too — especially when paired with Mantia’s qualifiers. Plus, zero stars plays better with the idea that if you don’t have something nice to say, you shouldn’t say anything at all.
