Xiao long bao at DTF is poor copmpared to the crystal jade and
imperial treasure, so avoid it.
Prawn fritters are nice, so is the yang zhou fried rice. But
everything there is pricy. If you're there for the la mian and
you've previously tasted those at CJ and IT, then it's more or less
the same standard.
Their hua tiao jiu chicken is not as 'toxic' as the other two: they
marinate with less wine, so it preserves the original taste of the
chicken.
Other than that, cost-wise for 5, assuming one la mian for each and
4-5 side dishes will be ard 110-120 bucks, budget.
