Today lunch

Since a long holidays, Chuseok, a Korean thanksgiving day, I have been slammed. To save time, I picked sandwich for a lunch and I wanted to have a new menu for lunch today. A few weeks ago, I saw a fancy sandwich shop opening near my company. 
I thought I will visit there soon. As soon as I got to that shop, I ordered a signature menu an by unattended order.
It melted on my tongue, it's out of this world.
The one was tastier than I expected and it's worth a return visit.

Some sentences were changed to replace some wordy, faulty tense sequence and unclear sentences. As well as to make it more simplified.
