The food at Jep's is fantastic and it's a great setting. We eat most of dinners here when we are in Samet, which requires us to walk 30 mins to get there - so yes the food is great. Their Indian dishes are fantastic and have a bit of a Thai twist and are delicious.
However, the staff are shocking and take forever to come to your table and are not at all friendly - actually the opposite. But I would prefer good food over good staff any day.
