Within Nepal, at least 93 different languages are spoken, but the mother tongue is Nepali. Around here I've only heard people speaking in Nepali, but many ethic groups have their own language. For example, in Chitwan, the Tharu people spoke Tharu, and in Tangting, the Gurung people also speak Gurung.
Nepali Rupees (NRS) is the currency used in Nepal. It's been going up over the past couple weeks, but last time I checked it was about 1 USD to every 113 NRS.
Actually, I'm not sure. We don't buy bottled water here because most brands are unsafe to drink. We only get water from our families and from the program house when it has been boiled and filtered. If we're at a restaurant, we order boiled water and might still iodize it. Soda, however, is safe to purchase and most bottles of soda are about 25 NRS or less than 25 cents.
We had an amazing meal at a cafe near the Rato Bangala school, a very nice private school. I love having daalbhaat (the typical rice and vegetable meal) everyday, but this meal was the best mainly because it was different! It was several courses of vegetables, fish, noodles, chicken, and a chocolate cream puff with milk tea for dessert.
