I wasn’t clear on which side of Queen’s Park you meant. North of Queen’s Park is the neighbourhood of Yorkville, which is more affluent and the restaurants reflect this kind of price point. Amal is an upscale Lebanese restaurant with lots of vegetarian-friendly options. Planta Yorkville is entirely plant-based. Although a little hit or miss, it’s an option to consider. You can read my report on it here. There’s also an Eataly just northeast of campus that has several casual restaurants with vegetarian-friendly options. Just south of there is Okonomi House for Japanese comfort food, assuming your vegetarian is OK with eggs.
East of campus and Queen’s Park are mainly chains and cheap eateries. However, Darvish is a quiet, unassuming Persian restaurant on Yonge St. that has quite a few vegetarian options on the menu. Ethiopia House has a decent vegetarian platter, with an assorted of different stews.
South and a little west of Queen’s Park and campus is the strip along Baldwin St., between Beverly St. and McCaul St., which others have mentioned above. I’ll add that it is worth going to Hattendo for their Japanese cream buns. There is also the original outlet of Kinton Ramen, which has a few vegetarian options.
Others above have made some good suggestions about west and southwest of campus.
