All taxis are yellow and some are very old. The minimum fare is 1 dollar, which should pay for a 20-minute drive. At nighttime prices go up and fares have to be negotiated in advance. Two dollars should be enough for a 20-minute drive. Many addresses have house numbers, but I haven't discovered any logic in them.
Some houses have even two house numbers.
Off course the local Ecuadorian cuisine is worth a try, but you can also find Mexican, French, Thai, Israeli etc restaurants in Quito. Many Ecuadorian restaurants have a set menu, which is cheaper than eating a la carta . A set menu should be 2 dollars or cheaper and often includes a starter and a drink. Sometimes restaurants add service charges and VAT to their prices. Although usually this is mentioned on the menu, it is worth asking if this is included.
