Dayali makes Peking duck as well as I've ever had it, even in China. If duck is your priority, go there and try all the unusual condiments that come with it.
If good service is part of your enjoyment, maybe get your Peking duck elsewhere. It flagrantly favoured Chinese guests and larger parties. We were 2 and nearly the only non-Chinese, so I practically had to trip a server to get some attention. English proficiency to explain foods was a problem, but hardly unique to Dayali.
If you want more than duck, the rest of the extensive menu was intriguing but much of it was unusual and we're versed in Chinese cuisines. A mixed vegetable and a fried rice dish were very good, as was a novel (to us) cold fungus. We'd like to have tried others but I asked our server about a few selections and was told we wouldn't like it, so we stayed with the more or less familiar. I'd gladly go back as part of a group including Chinese as cultural bridges.
