I have been twice in the last week. They are open from 6am until 2pm (days of the week I don't know). I arrived the first time at 12:30 and most of the "good" dishes were gone. What was left was plain cooked vegetables without spices or in a curry/coconut sauce. I was disappointed.
The second time, I decided to go at 11:30 and was able to find a curry dish and an interesting dish with lots of mixed veggies. It was MUCH better and very happy with the taste. Very similar to the taste found in other veg. restaurants in town. The noodle soup (with some tofu and lightly cooked organic greens) and a nice tasting broth which you finish off to your own style was free as someone sponsored it for the day. I paid anyway. :-)
2/3 vegetable dishes and rice is 10/15 B.
Noodle soup is 10 B.
Different drinks are 5 B and smoothies are 10 B (some sugar free) (served in small glasses.
In the front they have some very nice flowers including beautiful orchids. Inexpensive organic produce is for sale as well as staples, spices, unusual herbal teas, kitchen items and health care items (including an inexpensive spray for mosquitoes - located to the left of the front entrance all the way on the back wall - I think on the middle shelf).
Overall a very nice experience if you get there early enough to get more interesting/flavorful dishes. Some of the staff spoke some English. Worth at least twice the price charged.Pros: Inexpensive., Basic but big facility., Lots of smiles from staff.
Cons: Better dishes run out first.
