Whenever I'm in UP Diliman, I always make sure to go by the shopping center or SC, for those in the…read moreknow, for fishballs and a shake at the very appropriately named Healthy Fruit Shakes stall.
The second best part about the shakes here is that they are customizable: they have a great variety of shake ingredients you can choose from, which you can combine for your drinking experience. You can totally create some bizarre Frankenstein's monster of a shake and they'll do it for you. The "healthy" and "fruit" in the your shake here are certainly relative, as there are options like milk chocolate chips, cookies, and cheese, as well as the usual, much more nutritious fruit and vegetables. They add sugar syrup and milk to the shakes most of the time, and you can opt out of either of those as well.
The first best part about the shakes is that they're CHEAP. A twelve ounce cup is around thirty to forty pesos, which is likely half of what you would pay for in most other shakeries, and the price of bigger cups aren't that much. Even for non-local or seasonal fruit like strawberries or kiwis, it's still the same price, and another ingredient to your shake is just a five peso addition.
It can get a little hot and cramped in their tiny stall, but at least you know the stuff is fresh since you're surrounded by their produce, which you can buy as well, and their makeshift order and payment system is pretty efficient. Whenever you're in the area, just look for the last shopping center stall closest the UP COOP.
