Homemade beef hot pot - Korean style

A few weeks ago I bought a Korean cookbook (in English, of course). This was my first attempt at making something out of it. Although this is a bit of a modification due to ingredients on hand. I was aiming for a beef hot pot type dish, similar to ones I have had at Korean restaurants. It turned out remarkably similar to what I've had, and we both really liked it.

Korean-style beef hot pot
1 package of beef bulgogi (thinly sliced beef)
1 package mushrooms
6 green onions

Season beef with a mixture of equal amounts soy sauce and sugar, 1-2 cloves garlic (crushed), several finely chopped green onions, a half teaspoon of sesame seeds, and about a half teaspoon of sesame oil. Let beef sit in seasoning mix in refrigerator.

Slice mushrooms, slice remaining green onions into 2-3 inch long pieces. Put beef, mushrooms and green onion in a large sauce pan. Add 1 cup beef broth and enough water to just cover (can use all water if no beef broth available). Bring to a boil. Turn heat down to medium. When it comes to a boil again, add a tablespoon or so of soy sauce. Stir, and serve with rice.
