I wish I did something similar to this when I got married. I would love to have an array of seasoned meats and salad for the guests to choose from! Food services can be pricey, but it all depends on where you go and what you want.
Hot Dog Bar-" I actually did this for a SuperBowl party and it was a HUGE hit! Crushed Doritos was a favorite topping :) I kept the hot dogs warm in a crockpot. " would be cute as a "hot diggity dog bar" for a mickey party too!
