We have tried Grilled Cheese Sandwiches around the world, but the 3-Cheese Grilled Cheese Sandwich at the Toasteria Cafe' in Taipei is in a league of its own. Once a small little sandwich stand less than a mile away, now they have a full scale restaurant that is packed almost everyday.
On a sad note, however, recently they changed their menu and took our favorite sandwich off and replaced it with another. While their other grilled sandwiches are also special, and still delicious, we've had to downgrade our Yes to a Maybe. Hopefully, someday they will add our beloved 3-Cheese Grilled Cheese and Spicy Grilled Cheese Sandwiches back to the menu again.
The lesson here is that you have to enjoy a favorite sandwich while it's here, eat it as much as you can, because it can be taken away at any time.
