There are many choices of food here freshly made. The food isn't that salty compared to other places we've been to. Orange juice (laranga) is very refreshing. We went there a bit late for lunch and the place is still crowded. It seems to be popular among locals too. They have promotion if you come early. The complimentary coffee and tea are provided on the way out but don't taste that good. There is also a free wifi.
For food by weight restaurant, the paper bill will be given at the gate. Bring it along with you. Start choosing what you like. We recommend rice and chicken here. You can walk around to see what they offer before start taking anything in you plate. Bring the dish to weight station. They'll record the price on paper bill. The price per gram of dessert is higher. Some place even separate the plate for salad and appetizer from the main dishes. You can order drinks from your table. Normally they don't speak English so better prepare some basic Portuguese words to order.
Totally recommend this place. We love many dishes here. The price is so reasonable too.
