Re:How do you keep track of your favorite restaurants?
Back in the early 90's when I first learned to use a spreadsheet for work I started making a list of places (including restaurants) in New Jersey that I wanted to go to. At the time it was primarily intended to keep track of places to take my kids. Over the years it's evolved into mostly a restaurant list (the kids are grown now) with over 1200 places, about 800 of which are restaurants. I've been to about 80% of the places, the others are on my perpetual "to do" list. I'm still adding to it, and also making a note when I hear of a place closing, and occasionally dropping a place when I see bad reviews.
Over the years I also expanded it with tabs for PA, Philadelphia, NY City, Upstate NY, Long Island, and CT. In other words, anywhere I'm likely to make a day or overnight trip.
So, I'm always set. It's been my go-to guide for about 20 years, I refer to it almost daily.
