>>21490900 (OP)Steakhouse food, I think. I'm of the mind that there really isn't anything served at a traditional steakhouse that you can't make as good as home with a little practice. There is nothing on the menu there that requires special equipment or technique that is not common to home cooks. Which is what traditionally made Steakhouses so decadent, I think - it really is a silly meal to buy out if you've got any cooking skill.
