Personal highlights

1. Lhasa by Night: surprisingly modern, clean and illuminated 
2. Shopping: many possibilities, street markets, and modern malls
3. Restaurants and cafes close too early, I have not seen any nightlife
4. Mobile Shops: it's impossible to get a SIM card for foreigners!
5. Saying goodbye to Tibet after a few short days...
