Austin - Dot's Place and the Boiling Pot
I don't know anything about Dot's Place, but here is some information on the Boiling Pot. (I don't think there is a relation between the two..)
Although we haven't actually been to the Boiling Pot in Austin, we have been to the Boiling Pot (original) in Rockport/Fulton TX (owned by another 'Dot'; Dot's son, I think, runs the Austin location). The Rockport Boiling Pot has always been excellent. Spicy Cajun boiled seafood (shrimp, crab, crawfish), potatoes, corn on the cob, and sausage. They dress you in bibs, seat you at a table adorned with condiments, paper towels, butcher paper and crayons to amuse yourself while you wait, bring you beer, and when the food comes, which is ordered by the 'bowl', they dump it out onto the table and hand you wooden mallets. The Rockport restaurant is next to the bay and is open and breezy, decorated with crayon artwork from the tables, and with walls covered with miscellaneous crayon graffiti. There is a guy there who shucks fresh oysters upon order as well! (Below is nifty photo we took of him once.)
We go to this restaurant every time we are in Rockport visiting family (we live in San Francisco). I honestly say that it is one of maybe 4 of the absolute best restaurants we have ever been to in the world (in our humble experience). I would recommend the Boiling Pot in Austin if it is anywhere as good and fun as the one in Rockport.
