KFC是(得加上"是"或者破折号)很有名的饭馆("儿"在书面语中通常省略, 虽然在口语中北方人喜欢带儿化音)。 你以前一定去过那儿(I guess you meant "You must have been there")！ 它的中文名字("它的中文的名字" sounds awkward)是肯德基. 虽然它的名字比IKEA的中文的名字更不好听(Did you mean to say"不好听"?)，但(It should be noted that "但" can't be omitted when you have used "虽然" in the same sentence. However, you can omit "虽然" in most cases when you have used "但")在中国还很流行。 你在东方的KFC吃过油条吗？大概没吃过，可是在中国的KFC你可以吃油条早饭。中国人不都觉得卖油条很好的。人们有很多别的看法。有人说买的行(I'm afraid I can't understand what you said)，又有人说中国饭馆儿卖的油条更好吃。别人说一个必须花三元，太贵了，应该便宜点("更便宜" is used when it is currently cheap, so you cannot say "应该更便宜" after "太贵了")。 You can write it in a notebook entry so that corrections to it can be highlighted in different colors. Besides, why not provide your orignal English text to enable people to understand what you are trying to say better?

KFC很有名的饭馆儿。(KFC is more like a fast food restaurant,it's neither so high classified compared with those 5 stars restaurants nor like a local cheap restaurant,so i think kFC 很有名的餐饮连锁 is better,which means KFC is a popular chain fast food restaurant).你以前已必须去过那儿！它的中文(的 can be omitted,becuase there is no need to put two 的 together)名字是肯德基.虽然它的名字比IKEA的中文的名字更不好( i didnt quite understand this sentense,does that mean the name from kfc is no good than chinese ikea?)，在中国还很流行。你在东方的KFC吃过有条(薯条？potato chips?or 油条？)吗？大概没吃过，可是在中国的KFC你可以吃油条早饭。中国人不都觉得卖油条很好的。人口（people think different or the population thinks different?and obviously the later doesnt make sense xdxd）有很多别的看法。有人说买的行，又有人说中国饭馆儿卖的油条更好吃。别人说一个必须花三元，太贵了，应该更便宜。 well done!
