I'm looking for a restaurant near the resch center where I can get some vegetarian food

Sorry, I know there's a lot of post asking for food recommendations, I couldn't find what I was looking for in previous posts.

I'm coming to visit soon for a concert at the resch center and am hoping to find someplace to eat beforehand. If it could be walking distance that would be awesome (I know that may not be possible though). The restaurant wouldn't need to be an actual vegetarian restaurant, just something with a meatless sandwich or something.

I really like the veggie burgers where you can see chunks of vegetables in the patty (like Culver's. But not Culvers bc I live in Milwaukee and can get Culver's anytime) but an impossible burger would do in a pinch!

Thanks in advance!
