Restaurant bacon is the thinnest option you can find, and it's usually cut into 1/32" slices. Because it's thin, this type of bacon crisps up quickly, and it's commonly found in diners, restaurants, and hotels. Regular slices are typically sliced into 1/16" pieces, and they are the type of bacon you'll find in grocery stores or residential kitchens, normally. Thick slices are 1/8" thick. Due to the thickness of the slices, this type of bacon is good for making sandwiches or for adding to pasta dishes. But, it also won't have the same crunchiness as thinner options.
