I am usually not a fan of buffets, but Journey is better than most. There are Americanized dishes as well as some more authentic dishes. The buffet also includes some American dishes and a HUGE sushi buffet.
If you are a sushi fan, the price is well worth is for all you can eat. The sushi is above average but mostly Americanized sushi. Most of the sushi is cooked, but there are a few traditional pieces of sushi (raw fish and rice).
I was impressed with the selection of seafood and a big fan of the mussels. There's Chinese style desserts as well as Jello and soft served ice cream.
The place is usually packed with Asian peeps which usually means the food is pretty good. In this case, I think it's more of the fact you get a ton of food for very cheap.
Overall, probably the best Chinese buffet in Madison so definitely worth a visit!
