corr the english mistake

If you visit Egypt, you must eat the traditional and local Egyptian food. The Egyptian food like grilled meat and lamb chops are tasty.
And then you can ask the Egyptian how to cook the Egyptian dish .If you learn how to cook the Egyptian dish ,when you came to Hong Kong. You can cook with your friends.

---->

If you visit Egypt, you "should" (比較合理，must比較像廣東話用法) "try" (因爲try更有體驗的意思，用eat:是不是你到埃及，一定要吃埃及菜，否則會死?@@) the "local traditional" food (不用and).
The Egyptian food like, (可加逗號)grilled meat and lamb chops are tasty.
"Moreover" (moreover意思是仲可以,而and then通常用於一步一步的步驟說明, 你沒有交代請教之前做什麼,所以and then不適用) you can ask the Egyptian how to cook the Egyptian dish. If you "have learnt" (表示先學了) how to cook the Egyptian dish, "you can cook for (用for 是煮給朋友的意思, 你朋友冇學煮,點可以同你with 一齊煮?)your friends when you come back to Hong Kong (句子位置錯誤要前後掉轉,二合為一)"

亂碼: "should" (...........) "try"(.....)

if you prefer 'dish' then should be 'dishes' because you usually want to learn cooking few dishes instead of one dishbut I suggest to replace Egyptian food or cuisine .

it is very good i can't see any mistake!!!
