Here's an idea for a map-based app.
The other day I was walking down Columbus Ave, on the west side of the street, and passed an Italian restaurant that looked like a place I'd like. Just a neighborhood restaurant with waiter service, but nothing fancy. They have a place like this in Lexington, Mass that I like to eat at. And one in Mountain View, Calif. There used to be one of these in every neighborhood in NYC, but nowadays mostly they have are upscale places, which are nice, when you feel upscale. But sometimes you just want a plate of spaghetti with a couple of meatballs and a nice mixed salad with Italian dressing, a big glass of ice tea, for about $10 to $12 plus tip.
And there it was!
I looked back and made a mental image of the place. I didn't write down the name or address. Now I want to find it. What I'll do is slog through Google Maps street view of the neighborhood. But it would be nice to be able to take a virtual walk down the street, a little faster than I walk IRL.
Obviously this would have other applications. You get to play virtual tourist. Or do window shopping. Look for a nice nieghborhood to live in a town that's far away. Etc.
Update: Had a nice plate of spaghetti and meatballs on the 7th with Ryan Tate, at Francesco's. Hit the spot perfectly.
