The first few times I had their ribs they were awesome. Lately, they've been hit or miss. Seems Willy's might be getting a little inconsistent.
Either way, I use the Pineapple Willys recipe they run on Beach TV to make my own ribs... and they turn out awesome!
1 or 2 racks
Dry Rub (I use Bad Byron's)
Sear each side on the grill for 3 or 4 minutes
Put 'em in the oven @ 200F for 3-4 hours
The meat falls off the bone, tastes great... you won't even need any sauce.
