How can I make garlic butter similar to the Kobe restaurants?

My friend and I would like to make the garlic butter that they serve at Kobe's or something similar to it. Kobe's is a japanese steakhouse where they cook in front of you.How can I make garlic butter similar to the Kobe restaurants?
The hibachi chefs at my old restaurant used to take minced garlic, saute it with a little butter, then blend it with more butter and put it in the cooler to re-harden.
