My favorite shop is one that was incredibly successful and my first hotel shop and I'm probably a little sentimental about it because my Mom was with me and I miss her terribly. It was at the George Hotel in DC and we made a great weekend out of it. It was a pet friendly hotel that had a happy hour and so sitting in that hotel lobby sipping wine and seeing dogs peering out of bags with my Mom was one of my best experiences mystery shopping ever and I've not reached that high since.
Another favorite shop was at the Rainforest Cafe in Atlantic City. I had to have an alcoholic drink and a regular drink and ask about a menu item. I ended up spending more than my reimbursement, but I had a great afternoon being the only person in the bar, drinking one of my favorite wines for $4, enjoying a great meal and a fantastic bartender. That was over a year ago and I've had that same experience at least once a month until everything shut down last month. Sometimes it's the simplest things that can be the greatest things.
