The area around Chatelain is always hopping with restaurants and the Tuesday we were there was no exception. We arrived around 9 and got one of the few remaining tables. The menu was pretty standard and we had some of our usual vegetarian suspects: loempias with dipping sauce, and hearty helpings of curry tofu. I opted for red curry, which was delightfully spicy and full of cooked (but not soft) vegetables.
There seemed to only be one server for the room, which meant it was rather hard to get his attention, but we weren't in a particular rush - and the food was served quickly once we managed to place our order. It was a comfortable setting, tasty food, and clearly a popular destination. I'm only sorry to have discovered it just before leaving!
