Their caramel pretzel shake is awesome. I was expecting something way too sweet from the description, but the saltiness and the crunch of the pretzels really balances it out well.
I didn't quite enjoy my Morty's Steakhouse burger... I prefer simpler burgers with no condiments where you can really taste the meat. The meat itself was perfectly pink and juicy but I didn't like that the bottom bun was soaked with grease. Also wasn't a big fan of the Haystack Onions (I've had better onions that style, from Flour in Boston). Overall, it was fat overload, especially with the shake.
I would like to try a custom creation next time, without any sauces or fancy toppings (and no shake - that thing is a meal of its own!) I actually enjoyed the cracked peppercorn rub a lot - flavorful without being overpowering - and I'm curious about the other rubs, too.
