Thanks I'm also looking for a moderately priced lebanese restaurant.
There is one lebanese restaurant, Ali Baba in the centre of town, would you like to book that?
I would like to get the phone number for that please.
Sure! The phone number is 01 462 432565. Would you like me to book a reservation for you today?
