Just updating this thread as my BBQ Pork Bun hunt continues.
Crestview Market sells the frozen BBQ Pork Buns that I've bought in many metro areas. Very passable if you microwave them and always fantastic if you steam them. These will definitely tide me over until I find the fresh version!
Ichiban Bakery in Kenny Road Centre had a good serviceable pork steam bun, but it was not a BBQ pork char siu bao. The filling was closer to what we call Pork Hash in Hawaii.
Ditto with the pork steam bun at Golden Delite Bakery on Bethel and/or in Gahanna, but the Golden Delite knocked the Ichiban version out of the water. Much better spices and it tasted fresher too. It still wasn't a BBQ pork ball but it's a start.
So today the husband and I headed to Ying's Teahouse and YumYum in Clintonville. The homemade dumplings were out of this world, possibly the best I've ever had anywhere including in Hawaii. I will go back just for the dumplings! Ying Ying had steamed pork buns AND bbq pork buns on their appetizer menus, but they were very expensive ($3.00+ for two small but freshly made steam buns). I was not impressed with their bbq pork bun--it was sickeningly sweet, it was doughy even though it had been freshly steamed, and it was just generally gross.
So far Golden Delite is the best of the bunch.
