I would recommend you go here once at least and decide for yourself if its cool or not. So in that way Tubby Dog isn't on the avoid list.
BUT, I always leave wondering what exactly they are trying to be? A semi-bar? A "unique" food destination? A trendo-scenester hang out? OR all of the above?! Hahhah.
SO you can get a HUGE but overpriced hot dog with captain crunch cereal as a topping. I suppose this makes you trendily "weird" in a cool, funny way to order such a thing. Also, you can order a regular sized can of beer for about $6. Occasionally, you can see a local band play here, stuffed into the back corner of the place with no stage or real floor area.
Mainly "alternative" scenesters hang out here, but late at night klub douches may swing in for a hot dog to soak up all the Jagger-bombs.
I'm sorry, the hot dogs here just are not as great as their reputation, and are certainly overpriced.
Like I said DO come here and decide for yourself, but if you MAY be disappointed :)
