We enjoyed our trek out to the Santi Asoke temple and surrounds. The temple itself is an oasis of calm, coolness and quiet and features a massive waterfall at its heart, with communal space around it to chill and take in the energy. Surrounding the temple were various small shops selling natural products, ready to eat foods and organic fruits and veges. At 4-5pm when we visited we found 3 vegetarian eateries. One was a very simple noodle shop on the main road - the noodles were cheap and quite tasty (felt a bit Chinese in flavour but I might be wrong). Across the road there was a restaurant and natural products store called Asoka, where we tried a green curry and a vegetable stir-fry - we asked for no mock meat in both so it was thankfully absent. The green curry was *very* firey! Not bad but not fabulous either. The vege stir fry tasted like your average Chinese fare, so much so that we secrectly suspected it probably contained MSG (the sauce for the noodles across the road did, it was listed amongst the ingredients on the bottle, so we skipped it). There was another restaurant on a side street nearby but it was closed - apparently they close at 4pm, so maybe we'll try it next time.
We bought some awesome organic passionfruit at a nearby store - they were super huge and taste great.
To get here, we took the subway to Phahon Yothin (a few stops before the Chatuchak markets), then got a taxi for about half and hour (cost us 111 baht one way). Nice little day trip from central Bangkok.
Cons: Far from central Bangkok, MSG?, mock meat
