Guzman y Gomez's free double protein upgrade covered every main and mini ordered through the GYG app, and excluded tacos and quesadillas. It started on 18 March 2026, was extended to 5 April 2026, and it has ended. The exclusions are the part people kept getting wrong at the counter.
It ran until 5 April 2026. We keep the page up because people still search for it and the details are worth having, but do not make the trip on the strength of this article. For what is actually on right now, see things to do this weekend.
Mains and minis were in, ala carte or as a meal. Tacos and quesadillas were out. That is not arbitrary: a taco is sold in threes and a quesadilla is a fixed-fill item, so doubling the protein on either breaks the food cost in a way a burrito bowl does not. It also could not be stacked with any other promo. The full mechanics of the upgrade, what it was worth in grams and what Double Protein costs now that it is a paid add-on, are in our GYG double protein explainer.
It ran at all outlets but only through the GYG app, which is now the default shape for chain promos here. GYG has around 19 outlets across Singapore, spread through malls and the CBD, so the reach was real. The catch with app-only deals is timing: by the time a two-week promo reaches you through a repost, you are downloading an app with days left on the clock. Having the app already installed is the whole game.
Our post on 30 March said 31 March, which was the original end date. GYG extended it to 5 April 2026. Double Protein stayed on the menu afterwards as a paid upgrade, so the item did not go anywhere, only the free part did.
· Double protein works on a bowl. In a burrito it stops closing and you end up eating it with a fork.
· Tacos and quesadillas were excluded. Check the exclusion line before you queue on any chain upgrade promo.
· App-only deals almost never stack with other offers.
· Install the app for the one or two chains you actually eat at. Two-week promos are won by whoever hears first.
Tacos and quesadillas. Every other main and mini qualified, ala carte or as a meal, and it could not be combined with other promotions.
It ran from 18 March 2026 and was extended to 5 April 2026. It has ended.
Yes, but as a paid upgrade. Double Protein stayed on the menu after the free promotion finished.
