Consider Zyng as an overpriced Thai Express. I had the soba noodles with grilled chicken and spicy peanut sauce, and it was fairly disappointing. The food wasn't flavourful, the proportions were small, and the chicken was dry. Equally disappointing was the vermicelli with grilled chicken that my friend had.
The waiter we dealt with was also quite crude. As we had placed a takeout order, we had declined to tip because no service had been provided. Immediately after paying for our meals, however, the waiter processing our transaction asked us forthright whether we would be tipping in cash now, or tipping later. This is really poor waiter etiquette, and while we acquiesced, we should not have been asked that question at all.
