For a quiet, not-Vegas kind of thing to do on a Sunday morning, Ethel M's is a good choice. The factory line was down, and some kid was leading a tour group through. He was unintentionally amusing because he was sooooo unprofessional. I was intrigued by how much the factory line looks like a well-run scientific laboratory--lots of equipment and dials and spotlessly clean.
The cactus carden didn't have a whole lot of varieties--I'd hoped for more cactus species and more xeric plant varieties. Still, it was pleasant enough.
The highlight was buying Ethel M chocolate to take home. Not everything is superb, but they do have a few selections that are excellent. My recommendations: the white chocolate/cranberry/dried fruit/nut bark--that's a five-star item. Same with the lemon creams and the liqueur cream-filled chocolates. Sometimes their featured flavors (right now cocktails--I wasn't impressed, but the previous line of tea-flavored chocolates were wonderful) are amazing. Sometimes they are underwhelming.
