Burger Underground

"The service was great! My server (Jamie) was awesome! Was very attentive, not just me but all of the other tables which she had 5 or 6 others. She was very personable, with a great personality. The manager was sitting at the bar as well which is where I was sitting. He helped her a lot in getting food for the tables. He was also very nice and personable as well. I definitely recommend this place and need to check it out for yourself rather than looking at all the negative reviews. Because the service for one person is different for another person."

"Good burgers, but a bit pricey. However so is everything else in quaint downtown St. Charles. The self-serv beer dispensing machine is worth trying out. One of the employees explained how it works. They tie an RFID card to your credit card. You put the card on a reader, then select the beer you want from some small LED displays, and you are charged by the measured pour. Nearest similar machine is in Chicago. The software came from a vendor. Very interesting and unique."

"Really enjoyed the food here! Our server was great. We used the free pour option which we enjoyed. We'll be back this wknd for the live music & drink specials with some friends to try that out. The bath rm coulld use a little attention but all in all a really great place for our 1st experience!"

"We had heard about this place when they were operating out of another restaurant and finally got a chance to try it out. Service was mediocre, but they only had 1 person working the front end. We were never offered refills or asked if we wanted something else to drink, but she did get our orders right. We tried the appetizer sampler, a Mushroom Swiss burger, a Dug Out burger, and the Underground Trainwreck burger. For the appetizer sampler, you get to pick any 4 appetizers and we chose fried pickles, pepperjack cheese balls, jalapeño Mac and cheese bites, and southwest chicken bites. They came with ranch and a southwest sauce and each was a good portion for a sampler. The fried pickles were a sweet pickle, which isn’t our favorite, but everything else was really good. Unfortunately, the appetizer were the best part of the meal and the burgers were lacking. We actually tried to order 2 chicken sandwiches with a burger and were told they were out of chicken. The burgers are not what I would consider “smash’d” but just a regular burger that needed more seasoning. If we came back it would probably just be for apps and drinks, but would not recommend the burgers."

"Weekend lunch. Place was slammed when we got there, they had "murder on main" going on. Seemed like a fun group, murder mystery group, dressed like the 1920s or there abouts. Since they were leaving as we were ordering, I doubt the kitchen was backed up, so food got out fairly fast. Server was super nice. Person at our table was very unhappy with the blue cheese salad. Dressing seemed very thin from the looks of it, not creamy as I think of it as. I didn't see how it was listed on the menu though. Burgers were good. EKG burgers were great value and good. Fries and tots could both use work. Women's bathroom was out of toilet paper and paper towels, I was told. This could happen after any rush. Overall, lunch for 3 at $70 bucks seems a bit high, but I'll be back. Will update after next trip. I love my main street businesses."
