Underdog Restaurant and Catering

Savior!!!

Food was fantastic! Service was great. No wait. Street parking was easy. Awesome vibe & dog friendly. The blackberry cider was a favorite.

The owner reached out to me shortly after the review to reassure that's not how they do business and I was refunded.
I'll go back for another try because the hotdog is actually the appropriate sized dog!

The counter girl didn't even acknowledge me to place my order. I believe the ladies that were in front of me left for that very reason. I asked for a hotdog with fries, cheese and jalapeño. She has been on her phone the whole time.
She gives me my food, no cheese sauce. I asked for it again, and she literally just stared at me. She takes my food and covers the fries in cheese. Didn't even look at me as she handed my food back.
I'm like, sorry to inconvenience you! Which I did not say. I stayed polite.
Get to work and my 1st bite ,the bun is soooo stale and hard, and my hot dog is cold! I had to microwave the dog for it to be edible.
Extreme disappointment.

If you know, you know! This place is strategically inside of Flashtacos Restaurant and it's a literal, hidden gem! I got to try their hotdog and burger and it does not dissapoint. This was a really cool find and the owner is super chill. It's a must try if you're in the Damen/North area.

Says there open but closed and charged my card on website for an order? Why not close the system down then? The lady wasn’t helpful at front. Change your hours guys. It’s not hard. Wouldn’t

Neat basement location below flash taco, the space itself has some nice old pictures and a simple but colorful menu.The food itself was very mid. Fries and dog could have been a bit more flavorful, but the bun was the big offender. It was partly stale and dry, not tasting good at all.Can only recommend this place if you really, really want a Chicago dog and can't get up the effort to go elsewhere.

Found underdog through flash tacos. Cute little hidden hot dog joint. Friendly staff and the food is great. Tenders are the best ?

Nice place, well priced, open late which I’m excited about, the guys working were super cool, and the chicken sandwich was on point. Glad it’s in the neighborhood, I’ll be back. ??

chicken tenders are amazing, the man working was so nice. will be back. he really made our night!

This place was closed last night and looked like it hadn’t been open in a while. Perhaps update this listing?

The staff was fantastic, and friendly! I was starving, so I got the Chicken Strips and Fries. Loved it!!!!
