為了做出自己滿意的湯頭，David將伊朗的香料加入台式紅燒牛肉麵中，一般的牛肉麵使用豆瓣醬、醬油以及中藥包，而「老外牛肉麵」是結合台灣與中東特殊風味的牛肉麵，就如同David與妻子的相遇，即使膚色語言不同，卻仍然相知相惜，一起牽手超過二十載，這樣的結合衝突卻意外絕配。
David added Iranian spices to the Taiwanese braised beef noodle, which is usually made with bean paste, soy sauce, and herbs.
Laowai Yipin Beef Noodle is a combination of Taiwanese and Middle Eastern specialties.
It’s like David and his wife’s meeting. Even though their skin and language are different, they still cherish and love each other and have been holding hands for over 20 years.
