MARVEL TRIVIA NIGHT — TONIGHT AT MAINSTREAM! 🦸‍♂️🦸‍♀️

The Quizfather is back at Mainstream Bar & Grill tonight at 8:00 PM for Marvel Trivia Night — and it’s also Wing Special Night, so you’ve got plenty of reasons to stop in.

Even if you’re not a huge Marvel fan, don’t count yourself out. Most of the questions are multiple choice, and the whole night is built around a fun, fast-paced game show-style atmosphere. You might be surprised how much you know once the answers are in front of you.

And the food? Seriously worth the trip all by itself. Mainstream has some of the best burgers around, but my personal picks are the Chicken Satay with sweet potato fries and Caribbean jerk aioli or the scallop tostadas. Both are ridiculously good.

Grab a team, grab some food, and come have some fun.

Marvel Trivia starts at 8:00 PM tonight at Mainstream Bar & Grill!
