Protip: it is off-menu, but you can actually ask them to add hashbrown to your toast! They need to cook the food and toast the bread and if the limited space they have, this is the best they can do.
But if you do see any stand-alone stalls that says Isaac Toast… please try! Each toast sandwiches at Isaac Toast are made to order, where the moment you place your oder, they are made immediately.
I growing up eating this sandwich and still remember when Isaac Toast just opened, it was a mind-blowing flavor.
