Lupa Waterfall, beware

Here's a rewritten version of your review in a more formal and professional tone:

"I recently visited the Waterfall branch of Lupa, having been to other locations multiple times before. Unfortunately, my experience was marred by significant delays in food service, with our order taking approximately an hour to arrive after placement.

Regrettably, the issues persisted as I discovered a foreign object, specifically a plastic tab commonly found on Tupperware containers, in my pasta dish. This disturbing find occurred midway through my meal, understandably causing concern about the kitchen's quality control and attention to detail.

While I have had positive experiences at other Lupa locations, this incident fell short of my expectations. I hope that the management will take steps to address these issues and ensure a better dining experience for their customers."
