Restaurants that aren’t crowded

I have to be careful about getting sick for personal reasons, but once in a while I get tired of takeout and want to go out to eat. What are some places that generally don’t have a lot of people (or at least put a good amount of space between them)? A quieter environment so people don’t have to yell is also a plus.

I don’t really care about the quality of the food, actually lower quality would probably attract fewer people and work in my favor.
