Myself and my Husband like to take £100 between us for each day. We dont always spend it all, but that covers evening meals and lunch time snacks with the occassional breakfast. All our drinks plus trips. Plus with the exchange rate being higher, it would go even further.
That amount lets us eat and drink anything when we like without holding back. We like quite a few drinks in the evening and can even be persuaded to have a few drinks or 3 in the afternoon
