There is a high end hot dog and hamburger restaurant that has been opening around town lately, called Portillo's:

I didn't see prices but since it is a really nice building and not a hot dog truck, I imagine it is expensive.
Checking the ratings, it seems to get so-so ratings rather than good reviews, generally based on the service rather than food quality. What my wife and I like to do is go to a decent sub shop and get ideas for making more interesting sandwiches. Maybe we will try this place sometime. Places around here seem to being well with social distancing, enforcing masks, cleaning tables and other things that get touched, etc. so I don't feel at high risk going out once in a while. For us right now, that might mean once or twice a month.
