As requested, more information : Vapiano Silhcity does what it does appropriately. The problem is that the concept is just not good :

• Service at the counters is neither friendly nor polite. Orders are taken in a mechanical/industrial way with even less consideration than in a McDonald. To improve : smile, welcome (at the counter, the reception desk doesn't matter much)
• Waiting for the pizza with a wifi remote disk is a gimmick that just emphasize the factory approach of the whole place. To improve : serve at the table, use the wifi remote disk or similar gimmick to know where to if you don't know the table number.
• The card also seems somewhat useless and is one additional gimmick to learn. To improve : Get rid of the additional card and pay at counter ? You already have to swipe a card anyway at the counter...
• Waiting time is random, sometimes slow, sometimes superfast, and anyway you won't all get your food at the same time. To improve : Dead end here, I see no solution to this problem, as the restaurant is actually divided into multiple small independant counters.
• Food is okay, but nothing exceptional. To improve : quality is not on par with actual italian restaurants. It does feel fresh, it's just not very well made. Super basic most of the time.
• This is not a place where you'll want to stay awhile and relax and enjoy your meal, everything is meant to be expeditious. To improve : Dead end here again, the whole concept is about rushing in and rushing out.

Vapiano Silhcity is, in my opinion, at best a canteen that serves mainly Italian food. I don't like the concept, I didn't enjoy my multiple experiences here and thus, that's 2 stars for me.
