Former England One-day skipper Hollioake's 65 not out off 41 balls steered the reigning Twenty20 champions to a 37-run win over their London rivals.
The match took place in front of a crowd of 26,500 - a tournament record and the biggest at Lord's in over 50 years for a County game, excluding One-day finals.
"It is fast-food cricket," said Hollioake, 32, in his final season before retirement, as he met the competition's detractors head-on.
"But sometimes a Big Mac (McDonald's hamburger) can be as tasty as a meal in a five-star hotel," he added after Surrey maintained their unbeaten record in the competition and nailed their place in the quarter-finals.
"It is important to play hard whether it's fast food or cordon bleu."
The Twenty20 Cup is the shortest form of the professional game and, as its name suggests, is limited to 20 overs per side.
It was launched in England last season to boost flagging attendances at County matches which, in common with domestic cricket around the world, have struggled to attract major audiences.
