Fortunately, I did not miss this restaurant. It is very close to our hotel. However, because I thought it was just a very ordinary restaurant, I ignored it. Later, I heard an introduction from a young girl at the front desk of the hotel. I just came to this restaurant to taste, the dishes are very good.
The best sandwich we've eaten in our lives was served within a few minutes. It contained chicken, eggplant, zucchini, and so many other things we couldn't distinguish. A sandwich shop should be like this place.
A sandwich and coke/beer for 5 euros are all handmade, in front of you. They usually don't use everything available on the menu, but the man at the back (the boss?) made a good choice.
