Are you sure it was real butter and not margarine? I have worried this about a few places I have seen using what I believed to be butter and it turned out it was not, also most of the “butter” I have received with meals and seen in stores here is actually margarine. Not trying to say you are wrong or be argumentative in any way and I apologze if it comes off that way, just trying to ensure I don’t get sick if I forget to say something to them. If youhavent tried the restaurant by the same owners Pailay and are still here or ever come back, be sure to check it out, they have a huge separate vegan menu and everything that I have tried has been amazing ?
