Housed in an old villa south of the archaeological site of Jerash, Lebanese House may be deceiving on the outside. Upon entering the villa, the extremely large dining area and abundant staff make it clear that this place is an establishment, and the menu further elaborates by naming a surprisingly long list of famous people and foreign and local dignitaries who have eaten there, including Jordanian royalty and Richard Gere, among others. It is one of the oldest Lebanese restaurants in Jordan, founded in 1977 by Antoinette Rami, a Lebanese woman otherwise known as Umm Khalil. She brought traditional recipes from her homeland to Jerash (perhaps as she fled the civil war?) and opened the restaurant. More importantly, the cuisine is very authentic and extremely delicious. My only disappointment was dessert, which was practically nonexistent, but otherwise, the meal I had here was one of the best in Jordan. Even if the magnificent Roman ruins were not nearby, Lebanese House would still be worth the 45 minute trip from Amman...
In most tourist hotels and restaurants, there always seems to be a buffet available of varying standards. The food in this restaurant was pretty good and quite a lot of choice.
You can eat a lot cheaper if you go to local places rather than tourist places, and I mean a lot cheaper, but this place was about 10JD for 3 courses and I'd recommend it as you will spend a lot of time walking around the old city and might not fancy the walk into the new town.
I was starving when I walked in here. Situated at the center of the tourist bustle, Jerash Resthouse offers an outside and indoor seating. Basically you grab a plate and load up at the buffet. They offer a variety of local foods as well as a nice attempt at Western style cuisine. I found their stir fry with noodles very tasty. At the end of the line, there was a nice desert tray with some awesome pastries. A guy was making chepati's as well so I had to try some.
I had mostly vegetarian stuff as I was leery of trying meats in a foreign place.
Go to the Green Valley Restaurant for a great meal. This roomy restaurant offers a large variety of Arabic food. I had a variety of dips with my special person and loved every one of them. It was a nice departure away from the daily cycle of donairs and kebobs that I eat.
