Research for my Columbus Alive roundup of the city's best sandwiches served on pretzel rolls was long and exhaustive. Here's a look at some of the pretzel roll sandwiches I tried.

Research for my Columbus Alive roundup of the city's best sandwiches served on pretzel rolls (check it out here) was long and exhaustive. Here's a look at some of the pretzel roll sandwiches I tried. Pictured above is the Pretzel Reuben at Liberty Tavern in Powell. Mine's turkey but you can also get it with corned beef. And it usually comes with fries, but I'm trying to be healthy!

I really loved the Kobe Chorizo Burger on a pretzel bun from De-Novo Bistro.

Lexi's Hungry Bavarian isn't nearly as jaw-dropping as their corned beef specialties, but this tasty sandwich combines a satisfyingly thick stack of Bavarian ham with melted Swiss and spicy mustard on a thin, buttery pretzel roll.

On my first trip to the new Arena District pub Three Legged Mare, I ordered a half-sandwich-half-soup lunch combo. My corned beef sandwich came on an attractive pretzel roll, and my soup (a seafood chowder) was pretty tasty.

This guy came off a seasonal menu at the Winking Lizard: a Bratwurst Burger served on pretzel bun with potato pancakes on the side. Pretty great paired with a Great Lakes Christmas Ale.

And here's my photo of the Smoke House BBQ Luna Burger on Brezel pretzel bun at Hal & Al's. Not nearly as nice-looking at Alysia Burton's pretty photo that ran with my Alive story, but very tasty.

And, of course, you can't talk about pretzel rolls in Columbus without talking about Tip Top's Pot Roast Sandwich. But you also can't come close to taking as great a picture of it as this one by Will Shilling, so I didn't even try.
