DogHaus in Pasadena, just visited too, three dogs in two days...
I had the speciality dog with fried tempura onion rings, avocado, and mixed greens on 1/4 pound dog and it was really darn good, except for the bun, which was unique and interesting but a sweet hawaiian bread just doesn't work for a hot dog, i also had some chili cheese fries which were ok at best, i'm not a fan i've come to realize of the tommy's style of chili and this reminded me of that. though it was better than tommy's. (though sadly they were addictive after i tried a few and polished off virtually the whole dish, but it is very heavy, after that dog and a slice of rasberry cake and cappuchino from Europane i couldn't eat anything after that late afternoon lunch). i couldn't even smoke a postprandial cigar, which is amazing on a cold, chilly, almost wintery day. maybe next time i'll just order two of the speciality dogs and a soda and skip the fries.
Go with the tater tots.
I like their chili, and though I'm not crazy about the King's Hawaiian rolls for everything, it seems to work really well with their chili. Having tried several items now at Dog Haus, I have to say that I don't care for their natural casing dog. Each time I've had it, it's simply been too tough. Perhaps they just don't don't get enough turnover, but it always seems like it must have been overcooked to get that tough. On the other hand, I have (to my surprise) enjoyed their "regular," skinless dog, when ordered with some combination of toppings.

I had their Bourbon St Andouille and thought it was really good (and am addicted to their chili cheese fries (cooked well done with grilled onions on top). The sausages come on a great roll - maybe you can substitute that for the King's Hawaiian bread. Great chew - I think it was a French roll.
