I had once @360 cafe it was delicious and @The Cake Shop they have as well as hazelnut mousse and fraisier (strawberry & vanilla mousse) both amazing!!!
@Starbucks is also smoke free and the big one in Abdoun has a non smoking section that is large and comfy. Also technically @Turtle Green Tea Bar has a "non-smoking" section but it isn't amazing since the smoking section is just upstairs.
A professional and reliable place is located in Bayader @Body Clinic (065810535) I take my car there all the time, I find it affordable but depends on what work you need done.
You can find them @Virgin Megastore but sometimes they are out of stock so give them a call first. Also @Aladdin Computer Center but I don't know the price just give them a call too
@Cantaloupe Gastro Pub is a great restaurant with nice views and good food. A little pricey but the atmosphere is good especially for valentine's day
