Tried Biwon because we love all you can eat Korean barbeque. We upgraded to ayce sushi for 7 bucks as well.
There is a good selection of meats to choose from. Hit and miss there. The kalbi we got were thick and very hard to eat but the pork shoulder we got was great. The shrimp was also very memorable because it was bland and they weren't cleaned.
The sushi we will skip that next time we try this place. Didn't seem the freshest and the rolls were too drowned in sauce. I know some people like that but I'm not a fan of every roll having cream cheese and or mayo.
I noticed that this was mentioned in a lot of other reviews as well but they "were out" of the dessert again. If they don't have the items they should just remove them from the menu.
All in all we'd go back to try meats we didn't get and to give this place another chance.
