For a start it has a welcoming statue, the statue of Sveta Sofia (holy wisdom), a monumental copper and brass work overlooking the city. I liked it a lot.

The bulgarians seem to respect their past royalty. Several streets in the capital are named after czars (tsar) and kings (knyaz) : Tsar Simeon, Tsar Asen1, Knyaz Boris1, Knyaz Alexander, Knyagyna Maria Luiza.
They also seem to have respect for public property. Although everyone uses an i-phone, the phone half-booths are still in their place. I even checked a few of these pay phones and they were in order; apparently no vandalism. However, I haven't seen anyone there making a phone call.

Food is quite cheap, at least compared to where I come from. There's this chain of discount supermarkets scattered everywhere in the city, called BILLA ,where one can get good food at a fraction of the price. People buy there some wonderful croissantes for their morning and evening coffee; they even buy lunch as there is a grill facility in the store which offers hot grilled meat patties and other such products.

Sofia has a lot of souvenir shops, 'rose' items being the major souvenir on demand. Prior to departure, I bought a few souvenirs at the Central Market Hall (Halite). This is a covered, compact market in an historical building on Maria Luiza boulevard, across the big Mosque, and not far from the little streets making up the Ladies' Market.
