As far as this type of restaurant goes I vastly prefer Genghis to YCs. There are a lot of reasons why I prefer this place. One of which is that their meat looks much better then what YCs puts out. Also because it's not frozen there isn't a ton of suspended water content which means that when you get your food back it tastes better and the sauce isn't overly watery. Not to mention there is no freezer burn!
The veggies here almost always look more fresh then what I've come across at YCs. I love my onions and here they are crisp and freshly cut.
The portion sizes are a bit smaller, there is no denying that. But as far as flavor goes this place takes the cake from YCs.
