While I can't speak on behalf of the food, I can say that those giant daiquiri drinks you see people lugging around are probably the cheapest here. Based on my cursory assessment at least.
They don't offer the variety you'll find at other daiquiri bars (only four flavors), but their prices are a good $2-$4 less. And in such an expensive city, this certainly counts for something. To lessen the girliness of your daiquiri, you can add extra shots at $1.25 each as well. Make it a "Man Daiquiri" as my friend calls it.
I opted for a Strawberry + Pina Colada one in the smallest size (11 oz I think) and it was only around $11. It was on the lighter side in terms of alcohol content though, so if your tolerance is high and you want a buzz, I'd suggest adding in extra shots. Other than that, it was a delicious way to keep myself occupied while we wandered around the Miracle Miles Shops at PH.
They offer free samples too! FOUR STARS.
