In terms of food and value for money, probably. We enjoyed lots of different dishes including the favourites - sticky rice, pork and century egg congee, cheung fun, assorted buns and egg tarts. Steve loved the egg tart but I though the pastry to filling ratio was a little unbalanced with there being too much pastry but I've also had much worse egg tarts so it was still good.
With the right mindset Tai Pan is a good place for yum cha. If you're ok with being surrounded by large noisy families including children trying to squeeze between tables and chairs and ok with lots of people pushing their trollies round trying to vye for your attention and ok with grumpy service but in the mood for some good authentic yum cha dishes then it's the right place to go. If you want somewhere calmer with a more service based attitude then Red Emperor is a better choice but the food isn't as tasty and it's pricier.
