Go during the day or the weekend - you'll have more variety and selection. Price got upped: $3.75/donut. If you want one of their classics like the salt n pepper, triple chocolate or Homer they will likely have it on a weekday. Went on a Tuesday at 4:30pm and I bought the last Homer. Was dead quiet there, no music or anything but at least there was zero wait.
Next time I'll go earlier, go on a weekend, or call ahead. Wasn't really worth it but It was still pretty delicious!
