Entering the restaurant - you will see a very small place with 2 tables. Ones you order, the lady takes your order and starts preparing it. It is slow and for us, took almost an hour..
you can then go upstairs (from the outside) to eat in the open balcony - the lady will bring the food to you. you can take some beverages from the fridge or buy and bring your own.
Sitting upstairs is in a picnic tables and the food comes in disposable dishes. you can also decide to take is "to go"
All in all, this is a good experience and the food was good.
