I want to set a date for my parents. Are dresses allowed how much is the cheapest thing and most expensive thing on the menu and is it crowded and loud?

You can use open table ro make a reservation. The prime dinner and brunch times get filled quickly so if you have a very specific time in mind, make your reservation as soon as possible. Here's their web site link just scroll towards the bottom of the page to get phone number if you want to just call directly to make reservations. https://www.canoeatl.com/

Prices are between 16 to 45 dollars. Excellent restaurant. Sit at the outside bar for a truly delightful experience.

I can't speak for the cost of the menu. It's very upscale and very adventurous with their menu. I had an appetizer that had kangaroo meat, although I'm unsure if they still serve that. As for clothing, the restaurant mostly had people wearing button down shirts and polos. I believe much of the women wore dresses. The restaurant is not very crowded where you are sitting close to another. It wasn't loud at all.
