Ted's and Deco's are now outdoing each other in almost all terms to position themselves as then umber one, a title that easily belonged to the former for many years. Ted's having more branches here and in other parts of the country have the advantage and headstart while Deco's can't be taken for granted, being operated by the people behind the succesful Mang Inasal brand.
Ted's started to offer rice and combo meal is some of their branches to lure more people while Deco's decided up to bring "pre war" pan de sal and tie up with "Pa-a" bakery (famous for its pan de sal). Also the latter decided to target not only the lcoals but tourists and balikbayans for it opened a pasalubong shop right next to its flagship store in La Salette.
Now which is better? I can only speak for myself
For starters Ted's "presents" batchoy better. Ted's makes it an island while Deco's seemed to have been "tsunamied". See for yourself.
Ted's
Deco's.
Deco's on the other hand has better ambiance (since its new) and has better innovations. Loved their pre war pan de sal more than Pa-a's. cant be sure though but I think Ted's serve pan de sal by Tibiao bakeshop.
Taste? Ted's is more "saboroso" while Deco's is more subdued.
This may not have solved the "which is the best" debate so better try out for yourself. At least both serve extra caldo (soup stock) upon request.
