are cheaper and usually you can get them within 5 minutes of waiting. also they still taste good after awhile.
my recommendation is if you walk by golden gate bakery and if you see a short line, you should definitely get some egg tarts and you should eat them right away. if you don't have time to wait and if you are planning to eat the egg tarts right away, you can save yourself some time and money by going to the aa bakery.
