From our time in the land of Cleve, we visited The Lube a few times. The wings were always good, although we never tried the mega-hot variety...only the 2nd one down on the heat scale from there (the Suicide sauces at 30,000 SHU). I got the impression that not too many people may even order those, as the waitress gave me a wry look when I ordered a whole bucket of the almost-mega-hot ones.
Their sauces are good. We've tried the Suicide, Classic Hot, Cajun, and Buckeye BBQ (mild). All were worth the trip.
Which one(s) will you visit? We went to Valleyview a few times, and another on the east side whose name we don't remember.
If you're looking for a hot shop extraordinaire, head over to Chili's Fire Pit over in Mentor. Don's a great guy and has a nice selection of stuff in his store.
