BYMONEK,
Please, at least be honest with yourself!
The meal allowance given is far insufficient to pay for most of the hotel restaurant we are staying at.
Be honest, open your eyes and compare the menu vs what you can afford with the allowance (discount taken into account).
If you are honest enough, you will do, and get back here saying that indeed, it is most of the time impossible to pay for a normal dish + a bottle of still water, and please, do not jump over a meal, it is breakfast, lunch and dinner!
