We ate at Nan Xiang Steamed Bun Restaurant on ground floor. Here's some information about the restaurant from Senayan City's website:
100 special menu ala Shanghai arrived at Nan Xiang Steamed Bun Restaurant, the new restaurant at Senayan City who served not only the delightful food with an excellence Asian taste by the experienced chef from China, but also present with oriental modern ambience
The restaurant were very crowded because many people went there also (also in some other restaurant for example, Duck King and also Sushi Tei), but luckily we have reserved the place yesterday, so they already prepared the table for us. After a while, we started to order and we saw in the menu that it's quite expensive (perhaps because of chinnesse new year, i don't know), but the portion was quite big, so it's worthed with the price but too bad we were wrong. After the first menu was served, we finally found out the portion was so small.
While we were eating, we saw some kind of offering from Citibank for those who had a Citibank credit card. If you have those card, then you have a chance to get 25% off, 50% off, or even 100% off (means you don't have to pay anything). One of us had a Citibank credit card and my cousin take the dip and we got the Free dinner prize. We were quite surprised because we thought that it's very hard to get that chance, but we got it, so we didn't have to pay anything for the dinner.
Later on, i found out that most of the restaurant on that floor had the same offering from Citibank. I guess this had to do with Citibank's promotion in order to attract people to use their credit card. So if you have Citibank's credit card, why don't you try your luck in Senayan City? Perhaps you can have a free one like what i had today.
