Because I want to try as many different things as possible, I sometimes do "snack crawls" and hit a lot of places but order a small thing and share. The places are always take-out places with or without seating. I don't go to sit-down restaurants and order a tiny thing to share because I'm afraid the waiters will give me dirty looks and we'll be taking up a table while ordering something very tiny.
Are there any posters out there who do these snack crawls at sit-down restaurants? Do you just avoid busy times? Do you leave a larger tip? Do you get nasty looks from the waitstaff?
