Stir-fired beef or Lok lak varies in flavour based on the chef who prepares it. The dish is normally served along with fresh tomatoes, cucumber slices, lettuce and red onions. The beef gets its distinctive flavour from being marinated overnight in soy sauce, lemon, fish sauce, oyster sauce and pepper. If you don't eat beef the restaurants are more than happy to substitute the meat with pork, chicken or even tofu if you're a vegetarian. Similar to most dishes that you'll try in Siem Reap, lok lak is served with a fried egg, rice and a zesty brown sauce.
