I'm very disappointed by Sanchon. They raised their lunch price from 22,000 won to 33,000 won just because they're famous. Their food was neither fresh nor delicious. Only their environment and pine liquor pre-meal drink are worth checking out. The overall procedure and experience was too superficial.
If you're going for real delicious temple food, I highly recommend going to "Han Gwa Chae" instead, a nearby lo-fi and warm vegan buffet that is totally underrated.
