My wife and I were here a few years ago on one of our many trips to Pittsburgh and had to come back.
The first time I was there I had a Chicago Dog which was delicious. I can't remember what my wife had but it was so good she insisted we make it back on out most recent trip.
We stopped by around dinner time on Saturday and the place was hopping. We sat on the bar side which was even louder than the restaurant but fine for us to have dinner. The staff was all very nice and gave our option of eating outside, at a table by the bar or waiting for one in the actual restaurant.
Since my last trip I became a vegetarian and stick to a pretty strict low sodium diet so I didn't try the vegan hot dog (though I may next time I visit). I was happy to see the other vegetarian options which were on the healthier side. I ended up getting the grilled veggie salad which was so large I had it for dinner another night.
My wife (who is NOT a vegetarian) had Bacon Cheddar dag and a handful or fries pub style and said both were delicious.
We both had the draft root beer which is absolutely delicious.
Maybe it's because I'm not from the area but I don't think the prices are THAT high, for what you are getting the seem reasonable to me but I can see how to compared to some other places it may feel like you are paying a lot for what you are getting. To me it's worth every dime.
I actually love hot dogs which was the reason we came here in the first place but we love the food so much there that I am more than happy to get a salad or another one of the healthier options.
