This is a totally organic restaurant with an enormous selection of salads. Meat dishes too. For you vegans out there, some of the salads contain seafood, sausages, etc, but you can request those not to be included. If you scroll down on the Foodpanda menu you will see a 15 different selections strictly vegan menu.
It's a bit on the pricey side, but the superb quality and portion size makes it well worth, very well worth, their prices.
Their Pattaya location is in the Index Furniture mall, on Sukhumvit just north of Pattaya Klang. But you don't even have to go. In Pattaya you can order delivery via Foodpanda (see: https://www.foodpanda.co.th ). There are several locations throughout Thailand and they all have takeaway and delivery service.
I suggest taking a look at their menu on Foodpanda. An incredible selection of items - 55 salad selections alone, and plenty of additional selections too.
I tried their Northern Thai salad. I was not prepared for what I was served. I was expecting a medium size salad, but just look at it. It is huge. I was hungry when I went and I couldn't even finish it.

The photo doesn't do it justice. No matter how large you might think it is - it's larger - and absolutely delicious. Sooner or later I'm going to try every one of their salads.
I highly recommend giving Ohkajhu a try, whether you go or order delivery. I think you'll agree that it is superb and definitely well worth it.
