I walked past Sol Aztecas (2350 Frankfort Ave.) a couple of times this week — yes, I left my house even though it was a billion degrees outdoors — and saw one of those chalkboard street signs advertising two-for-one margaritas. The sign isn't always out front, but when it is, I can't think of many better ways to prevent yourself from melting in this heat. Well, not walking outside is probably another good suggestion.
