Toronto venues for anniversary party

I feel like there will be plenty of lovely smaller restaurants that would work really well for that, and also be super open to the idea whenever things open up. Depending on what sort of vibe or decor you're looking for, there are restaurants as hip and fun as Koh Lipe (two-floor Thai restaurant with a rose wall), Indie Ale House (west end, laidback and can do a nice selection of apps, not to mention a good selection of beers), maybe look into F'Amelia (downtown Italian restaurant with a patio/doors that open the space into a patio), or Godspeed Brewery in Leslieville.

If you have any other criteria, can probably list a few more ideas by the beaches, etc.

Are you completely opposed to a pub environment? We have some decent pubs and craft breweries where a lot of them serve the items on your list. The Duke Pubs around the downtown area, the Granite Brewery in midtown, Union Social, Amsterdam Brewery etc. We have quite a few lounges as well but they'll be pricier since it looks more "upscale" and in high demand entertainment districts so your dollar won't stretch as well. These would be places like Insomnia in the Annex, Reservoir Lounge near St Lawrence, all the KIng St joints, restaurants and bars in the Distillery District (which is also popular as regular wedding venues), etc.

Something casual but chic at the same time would be Art Square Cafe. It's a small art gallery across from the Art Gallery of Ontario and they serve appetizers, crepes and sandwiches, and other sweets. You can bring in your own alcohol if you get a Special Occasions Permit.

If you're open to sit down options, Greektown just east of downtown located on the subway line has tons of family friendly options in a lively setting that can work within your budget.

Give us a few food preferences and budget, and I can suggest some restaurants.
