How do you make a terrace poster that reads at a distance?

The terrace poster uses few words, a huge price and dark-on-light contrast, readable from the opposite pavement. It does not read if it carries the whole menu at table size. Step to the opposite pavement and mark what you can still make out. On a Madrid midday the poster is full and from the street it is only a blur. The offer, the price and the name remain, readable from that pavement.
