General manager Sean Brown suggests, if you really want a challenge, order the Signature Sandwich with a stuffed baked potato on the side instead of the house-made Old Bay chips. "Each of our potatoes is a pound to a pound and a quarter and comes stuffed with your choice of seafood, chicken or vegetables."
3: The J.J. Gargantuan at Jimmy John's Gourmet Sandwiches
6191 Old Dobbin Lane, Columbia, www.jimmyjohns.com, 410-872-0010
Created by Huey, brother of company founder Jimmy John Liautaud, the J.J. Gargantuan ($8.15) features Jimmy John's signature fresh-baked bread piled high with Genoa salami, smoked ham, Capicola, roast beef, turkey and provolone topped with onions, mayo, lettuce, tomato and homemade Italian dressing.
"We sell between 20 and 40 a day, and I'd say 99 percent of those who buy it are men," explained manager Mike Woizesko, who added it's a popular sandwich with those on low-carb diets. "You can order any one of our sandwiches as an 'un-wich' -- wrapped in lettuce leaves instead of on bread -- and the Gargantuan is really popular for that because it's just meat."
4: Our Famous Pounder at Cheeburger Cheeburger
8872 McGaw Road, Columbia, www.cheeburger.com, 410-290-6495
It's not unusual for a logjam to occur at the entrance of Cheeburger Cheeburger, and it has nothing to do with customers waiting for a table to open up.
"We have a wall where we post a photo of anyone who has finished Our Famous Pounder hamburger, and almost everyone stops to check it out," said Aaron Benjamin, one of the managers. "At times it can be hard to get people seated because they want to stop and see if they recognize anyone."
The Famous Pounder starts with 20 ounces of beef, which cooks down to 16 and is served on a 6-inch roll with your choice of more than 25 toppings. If you are 12 or older and you finish your burger, your photo goes up on the wall. Benjamin says they sell about a dozen a day and 95 percent of the people who order it finish it.
He adds that only about 5 percent of those who order one are women, and that the standing record is four in one sitting.
"A fellow ate four of them a few years ago -- that's 80 ounces of meat, precooked," Benjamin explained. "It took him two and a half hours and he also ate a small order of onion rings and a shake."
5: Smash Dog Pizza at Pub Dog Pizza and Drafthouse
8865 Stanford Blvd., Columbia, www.pubdog.net, 410-872-0364
If you're in the mood for pizza, you'll be glad to know Pub Dog's menu lists 21 10-inch thin-crust pies featuring everything from bacon and basil to grilled chicken and Gouda. And what's better than one Pub Dog pizza? How about two pizzas sandwiched together? A Smash Dog Pizza ranges from $15 to $20 and can be made with any combination of toppings.
"One of the most popular I've seen is our Dog Pound Pizza, which is like a meat lover's pizza, smashed together with our Wing Dog Pizza, which has boneless marinated Buffalo chicken on it," said Jason Tarazon, one of Pub Dog's managers.
He added that there's no mystery as to how it was created. "Our original location in Fells Point was one of the few places serving late-night food," he said. "After a night of partying people get hungry and ask for crazy things, like smashing two pizzas together. But soon, enough people were coming in asking for it that we put it on the menu.
"In Columbia we sell four or five of them a week," he added. "Usually late at night."
6: Ultimate Burrita Prenada at El Hidalgo
6060 Marshalee Drive, Elkridge, www.elhidalgorestaurant.com, 410-540-2999
Owner Ricardo Vanegas debuted this 8-pound, 2-foot-long burrito in July, but his original goal was the spring.
"We got delayed because I had to special order 26-inch platters that the burrito would fit on," he said.
Makes sense when you consider each one contains either Mexican or poblano rice, lettuce, tomato, pico de gallo and a choice of three of the following: shredded beef, shredded pork, ground beef, chili, steak, grilled chicken and shredded chicken. And, of course, it's topped with green and red sauce, guacamole, sour cream and more pico de gallo.
You have 60 minutes to finish the burrito ($39.99), and if you succeed, not only is the burrito free, but so is everything else the diner ordered, including alcohol.
In the first month it was on the menu, Vanegas served about 25, but the most anyone has eaten so far is about 75 percent. His advice to the curious?
"Before you come in, don't eat lunch. Don't eat breakfast either," he advised. "And pace yourself. A lot of people come in and start eating really fast, but they can't keep it up and have to stop. If you're going to eat the whole thing, you're going to have to find a steady pace and just keep going."
