Hi...IMHO, none of the big buffets are worth all the money unless you want over cooked food, tough lobster and marginal crab...
We love Crabby Joes on 192 just east of Celebration Intrance...fun staff, lots of action..loud and kids can be themselves...
For more laid back, try Shells, local favorite about 6 miles straight east of Disney on 192 is really good...
If you give in a do a all you can eat lobster, I would not do Angel's...Have fun...Ted
