Hi,
I am new to the food delivery places.
I am looking at a page.
There is a section called 'Japanese Curry' and it shows 'Curry and Rice' at $0.00 (but also shows Pork and Chicken Katsu Curry with prices).
What does this mean? You can add as many you like, and it won't change the cost? When you select it, there is no series of buttons that results in additional costs (e.g. Meat +$x).
It is nice to get extra curry and rice. Maybe they restrict it so you can only have one 'Extra' per 'Paid' curry? (or, maybe that is at least what they would like to do, even though the website does not enforce that)
The most likely solution is that someone entered the wrong values when putting in all the menu prices.
I'm sure if you advised the restaurant you'd see an actual price appear corrected pretty soon.
