I'm not sure if anyone's brought this up yet, but I just stopped at Catsup and Mustard with my friend the other night, and I was really impressed!
I ordered the barbecue-style burger (fried onions, bbq sauce, bacon, cheddar) and I LOVED it. The best part was that the burger itself is loosely packed so its VERY tender and juicy. I felt as though all of the toppings complimented the meat and it was just plain good.
You get vinegar slaw, a sweet gherkin, and another pickle on the side with every burger and I liked all 3. The slaw was tangy enough to cut through the richness of the beef, but not too acidic or sweet like most slaws.
Service and price were both pretty good, my meal was under 8 dollars and I felt pretty full afterwards! Plus, it looked like they have live music sometimes.
I'd give it a try :)
