Where can I get pumpkin spice?
I've seen it numerous places, most recently at @Zait & Zatar Superstores
Where can I find areas with a good amount of thrift shops/flea markets and is closer to west Amman?
Not really West Amman, but Buhtori Street at 2nd circle has sooo many secondhand outlet stores!
Where can I go alone and enjoy or meet new people?
