MOB {Marco’s Onion Burger} Grill, is an AWARD Winning, One of a kind Food Truck & Restaurant w/Serious Attitude | 2015-2021 So6ix Magazine’s #OkieHonorAwards #1FoodTruck & #1Burger | 2015-2021 Daily Oklahoman Reader’s Choice Top 5 Food Truck and 2017-BEST Fries.

The MOB Grill was “Commissioned to Satisfy” and created through the many years (since 2004) of Marco and his friends breaking bread {the main course being Marco’s Secret Onion Burger Recipe} together in various venues (from tailgates, parties, camp-outs, charity events, etc). Coming from a long line of family in the food business, it was almost inevitable that Marco Morrow would dive into the food world himself. When he did, it was with a food truck: MOB Grill! His beloved burgers had been a favorite of friends and family for over 10 years before MOB Grill was formed.

MOB, standing for Marco’s Onion Burgers, has been serving up burgers 2014 and have cooked over 200,000 of them and counting! We have a feeling that number will continue to rise once you’ve tried one for yourself. There’s something about the combination of Secret MOB Grill Marinade Recipe of caramelized onions on a juicy cheeseburger that makes you feel comforted. So simple, yet so delicious. Add a side of their Award Winning crispy twice-fried French fries and you’re guaranteed a great day. MOB Grill has won numerous awards every year since it’s inception: #1 Hamburgers, #1 FRIES & #1 Food Truck are ones they receive consistent recognition for. Once you give it a try, you’ll see why.

MOB Grill is co-owned and run with Seth Barker “the CAPO”, who has a passion both for these burgers and for people. You’ll often see him on the truck serving up burgers with a smile – say hello! Oh, and definitely don’t forget to say “HI” to his mom, Judy [we call her Momma B] who runs the register most days too (and keeps Seth in check)!

In addition to being out and about throughout the city, MOB Grill can be hired for tailgates, parties, weddings, charity events and so much more. Have a private event coming up? Your guests will love everything MOB. The menu has choices for all taste buds. You really can’t go wrong with any choice, but of course the original MOB Burger is a great place to start. If you’re feeling adventurous you have to try the Butcher, a MOB Burger topped with 12-hour pecan and mesquite smoked pulled pork. You’ll never question “Where’s the meat?” with this truck. Oh, and we should probably mention they’ve converted seven vegans so far – yep, their creations are THAT GOOD!

The MOB is back in town! Where will the MOB be? Good question, a sure bet is where ever you find the MOB, there will be great food and good times! Check out our website calendar to find location of the MOB Grill FOOD TRUCK

So why “MOB Grill” ? Several Reasons:
1) Acronym (Marco’s Onion Burger) Grill, it’s the REAL DEAL! No FUGAZZIs here!

2) The MOB of friends that have shared in this experience for over10 years and are an even bigger part of this now!

3) The MOBile concept of this being a Food Trailer (We like to say A Tailgate On Wheels)!

4) The MOB of people that will come and enjoy the MOB Menu.

5) Oh, and there might be a little play on words alluding to a Mafia type theme … but in order to be a part of the MOB, you must take an Omertá (vow of silence).

6) #howUdoin #MOBBEDup #BestBurgers #BestFries #BestCheeseFries #MobBossApproved #NoFugazzis
