I don't get very excited about subs in general but this hidden (literally) gem has 68 different menu items and their bread is very very good and easily among the best I've had. To find the place enter the nondescript office building (see photo) Google directs you to and go down to the lower level via the elevator in the lobby. Follow the mouthwatering smells from there. Totally worth it!

This is your sign. If you're looking for a new place to try today, it's here. I got the #19 +Jalepeños. ~$13 for a large sandwich and a drink. A small is plenty for lunch, I'm taking half home for later. Massive sandwich with tons of flavor. Looking forward to coming back and letting all my coworkers know about this hidden gem.

Great subs! Twice the sub for half the price. Always a quick in and out if you're in a hurry. If you want to dine in, they have a tv that's always running sports. If you're in the area, it's a great place to eat that isn't out of the way. Just go to 5680 and take the elevator to the basement.

Score! 👍🏼 Sometimes, you just get lucky! 😁 This place should be called What-a-delicious East Coast Italian Subs! I wish it was Wed or Thurs because I'll bet their chili is great too! After a LOT of years of missing and wishing for a great Italian sub shop, Google hooked us up with this little hidden gem. Buried on the lower level of an office building, you'd never know this place existed unless you worked here or trusted Google! 👈🏽 We are stoked that we find this place. The food/subs are excellent. 😁👍🏼

Great price for what you get, friendly staff and the food tasted really good. Got a sandwich and a salad today and they were both great. 5/5

#17 with no cheese. Nice portion. Taste great

So glad I stumbled upon What A Sub !! Great service, friendly people sandwich is awesome. The deli is a diamond in the rough one of those places you want to tell everyone but then you wanna also keep it a secret to yourself. Thank you for all you do.

My wife and I stopped here after driving down south for a vet appt, looking for a sandwich on the way home. After looking around for a minute in the lobby, we soon realized we had to take the elevator down a floor. I’m so glad we rode that elevator down to What-A-Sub! This place is amazing! Better that so many mediocre subs I have had in Denver. The ingredients are super fresh and the price is right. Easily one of the best sandwiches I’ve had in my 17 years of living in the Front Range. We’ll be back soon.
