The basic mannerism of any Restaurant is to atleast ensure that the guests are shown a place to sit, handed a menu and then served - how well these are done is secondary. Yo! China is the first of its kind that I have visited where it has failed on all three areas.
You can imagine that kind of service that existed when I say that they now have had to introduce token system for everything.
On the two occoasions that I went to Yo! China in Koramangala, I had to personally search the two floors for a place to sit, go and ask for a waiter to come with the menu and then ending up picking the menu from the next table. Once done, I had to search for someone who would take the order. When the food did finally materialize after an eon, it was just passe with one dish totally goofed up. It was also another first-of-its-kind where the appetizer was srved with my dessert. And the best part was that I could not find anyone to present me with my bill.
