Been to silk elephant and it's sister chain Bangkok balcony plenty of times, and the food here is good! I think the lunch menu is fantastic, gives you a wide range of dishes for 8.50 - 9.50$. Here is what is included in the lunch menu:
-Soup (usually they have a delicious tofu vegetable soup)
-Side salad
-Excellent vegetarian spring roll
-Entree (which is a smaller portion of most of the items off their regular menu)
I especially like their chicken with basil, and pad see eew. Their curry fried rice is another favorite. And yeah, the (red,green,pangang) curries are always good here. The ambiance is very nice, and the service is great! It was my favorite Thai restaurant in the area, until I Sukhothai opened up nearby, which I have grown more fond off.
