I went this past weekend, and while the service was abysmal (perfectly friendly--they were just seriously understaffed; we waited forever for the food, and the apps we ordered never came at all), we all loved our food. I had the mushroom-fontina-pancetta pizza, and it was absolutely delicious. As was the Italian sausage version I tasted. My friend's burger was also very good, topped with a nice blue cheese. Folks at the next table reported that their meatballs (Thai-style, I think) and pork sliders were "excellent."
The extremely slow bar service kept our alcohol consumption (and thus our overall bill) down, but I thought $7 for a (premium gin) martini fair. I do wish they offered more wines by the glass--only 3 or 4 per night. To our taste, neither of the two tried at our table was worth the $10 price tag.
Service issues aside (too early to judge imo), Mondo, w/its eclectic, reasonably priced menu, seems promising--esp. in the restaurant-deprived Lakeview. I'm wondering if others have been, what you ate, and what you thought?
